The ancient and medieval Khiva
The basic periods of historical development
Unlike many cities of Central Asia,
the historical past of Khiva and Bukhara was unknown
until quite recently. This was due first of all to
the lack of information about the history of Khiva
up to the fifteenth century and, secondly, to the
small amount of archaeological research, which was
only started during the 1950s.
Khiva was mentioned for the first time in the works
of the Arabic and Persian authors Istakhri, Mukaddasi
and Khudud al-Alam dating from the tenth century.
The archaeological excavations by V.A. Bulatova found
the earliest cultural strata of Khiva dating back
to the tenth — eleventh centuries. Meanwhile
Ya.Q.Qulamov stated, based on a limited collection
of ceramics, that Khiva was founded between the second
and third centuries A.D. It is important to note that
both V.V. Bartold and Kyat also dated the founding
of Khiva to the pre-Muslim period.
Numismatic finds and an interesting legend quoted
by Khudaiberdib. Khushmukhammad, the Khiva historian
(born in 1774), pointed to a more remote past for
Khiva. In his work Dili gharaib (The Heart of Rarity)
he wrote: «One more city, the city of Khorezm
(called Kami) was founded by Simb. Nukh (i.e. Sim,
the son of Noy), and is now known as Khivak. It was
formerly called Tarikh and Raml (a place abundant
in the sand). Once-upon-a-time, Sim b.Nukh lay down
and fell asleep. In a dream he saw himself surrounded
by three hundred torches. He woke up elated and, deciding
to leave a reminder about himself, he marked the place
and built a city. When he returned a second time he
built fortress walls around the city and dug a well
on its western outskirts. Khivak has been destroyed
and rebuilt many times.»
In trying to extract historical facts from the reports
of historians and legends about the founding of Khiva
and its founder Sim, we are confronted by the following:
Khiva was first of all known as Raml. However, one
should not fully trust this information because the
name Raml is often confused with the Palestinian city
Ramla. In addition the existence of Sim hints at the
possibility that it originated from Jewish legend.
This legend, ostensibly originating from biblical
characters, was subsequently attributed to Khiva and
a number of other cities and monuments in Transoxiana
in Central Asia.
Therefore, with regard to the question of the date
of the founding of Khiva, the most important criteria
to be considered are the findings of the archaeological
researchers. It should be noted that archaeological
excavations cannot be undertaken since Khiva is a
living city with densely built-up areas where only
stratigraphic methods of excavation and digging can
be employed.
Certain features in the cultural strata of Khiva present
difficulty for researchers. Its average depth is comparatively
shallow (6m. -8m.). The city developed continuously
over a period of one thousand years. The peculiar
formation of the cultural strata on the outskirts
of Ichan-kala, the historical center and initial core
of the formation of the city Khiva, indicates that
the cultural strata were not deposited in the same
way as in the case of the other big cities of Central
Asia. The earliest buildings of Ichan-kala were not
preserved, and the densely built-up area of modern
buildings prevents any wide-ranging, systematic archaeological
sounding of the historical site of the town.
In the restoration of a number of monuments in the
eastern and western sectors of Ichan-kala by V.A.
Bulatova, stratigraphic excavation methods were used.
This work revealed the cultural strata of Khiva down
to the continental layer for the first time. In lower
layers of the strata in the eastern sector only the
cultural stratum of the fifth — seventh centuries
was uncovered. These layers were directly deposited
on the pure layer of the dune sand. The cultural layers
of the eighth — fourteenth centuries, uncovered
in the western sector of the city, were also deposited
on the continental sand dune. According to Bulatova,
the territory of the citadel (Kunya-Ark) had been
discovered.
In the late 1970s and early 1980s, members of the
Uzbek Research Institute of Historical Monuments (UzRIHM),
found valuable ceramic material while working on the
restoration of the architectural monuments of Ichan-kala.
Studying the finds, M. Mambetullaev discovered the
ceramics came from an earlier period of historical
Khorezm dating back to the third or fourth century
B.C. During 1973-1975 the same scientist, while examining
the uncovered fortress walls of Ichan-kala, several
times found the brick work to be of raw square brick
40-43x40-43x9-13 cm, which was typical of ancient
Khorezm. It should also be noted that in 1969, E.V.
Rtveladze found antique and medieval coins in the
numismatic collection of a Khiva museum, which, according
to T. Sereda the curator, had been found in the region
of Ichan-kala.
Archaeological research aimed at determining the historical
age of Khiva was carried out in 1984-1990 by the archaeologist
M. Mambetullaev, a representative of the Institute
of History, Language, and Literature of the Kara-kalpak
branch of the Academy of Sciences of the Republic
of Uzbekistan. In all, he undertook six stratigraphic
excavations.
Excavation ?l, covering an area of 577 sq. m., was
carried out in the northwestern corner of Kunya-Ark
at the foot of a tall artificial platform on top of
which is the ruins of Akshikh-bobo. Ten strata were
discovered (counting from the bottom.) The first stratum
included the remains of the fortress wall. The wall
had been built directly on the continental coarse-grained
sand. The foundation of the walls is adobe with slopes
filled with sand and fragments of large raw brick.
On the foundation, double fortress walls were erected
from raw bricks of 40-42x41-44x9-13 cm, using clay
mortar to a thickness of 2-8 cm. The majority of the
bricks are marked with coats of arms. The width of
the inner corridor is 2 m. The inter-wall corridors
with blocked vaults are a widespread phenomenon in
ancient Khorezm fortification. They were found at
Bazar-kala (fourth — fifth centuries B.C.),
Small Kirk-Kiz, Burla-Kala (fourth century B.C. —
second century A.D.) and Kurghashin-Kala. In the historical
town of Koi-Krilgan-kala, built during the fourth
century B.C., vaulted blocks were used in the passages
of shooting galleries in the tower. The ruins of the
cultural stratum connected with these walls contained
quite a lot of ceramic fragments of red clay.
The second stratum was characterized by a strong defensive
system. The fortress walls of Ichan-kala were reconstructed
with raw bricks of 39-41 x40-42x9-1 1 cm to a thickness
of 0.75-1.80 cm. The shooting corridor and the inner
tower houses were also built with raw bricks. As a
result, the thickness of the fortress walls of Ichan-kala
reached 7.5-9 meters.
A third stratum consisted of the remains of raw walls,
uncovered to a length of 4.7 m., preserved to a height
of 2.55-3 m. and 1.1 m. in thickness. The walls had
been built from raw brick 34-36x35-39x3-5 cm and plastered
with a layer of large-grained sand containing fragments
of ceramics, and animal and fish bones.
The fourth stratum consisted of a loose layer, which
was 23-52 cm thick. It covered the walls of the third
stratum. It extends to the limits of the fortress
walls and contained ceramics from the ninth —
eleventh centuries. The layer on the crest of the
fortress wall reveals the absence of defensive walls
on the fourth building period.
In the fifth stratum one can see a section of the
wall built from small raw and burnt brick of 23-25x23-27x3-5
cm. The wall is 1.5-2.5 m. thick and 37-38 cm high.
The transverse raw bricklaying consisting of two or
three rows are found on the top of the earth wall
and filled with earth. Ceramic fragments, fish and
animal bones, pieces of glassware, and pieces of irrigation
ceramics from the twelfth — thirteenth centuries
were found. Apparently, repair work to the fortification
walls was carried out only in the area of Kunya-Ark
at that time.
The sixth stratum was connected with a period of destruction.
On the crest of the fortress walls Muslim burial-mounds
appear. According to Muslim burial rules, funeral
chambers were built with raw bricks (22-24x23-23x3-4.5
cm). Burial chamber no. 2 has a floor of double slopes
and burial chamber no. 3 was re-covered with raw bricks
(22-23x22x3-4 m) placed edgewise. Burial in wooden
coffins occurred. Almost all the skeletons were found
lying on their backs or on their right sides with
their heads pointing west — the direction of
the Kaabah. There is ceramic material from the seventh
— fourteenth centuries in the earth used to
fill the graves.
The seventh stratum featured walls, made from blocks
of mud and covering the burial places, preserved to
a height of 0.52-0.72 m. and 1.1-1.4 m. in thickness.
These walls are located on the external western side
of Ichan-kala, parallel to its modern walls. In the
layer containing the ruined walls, pieces of ceramic
and copper coins from the eighth — fourteenth
centuries were found. Six rooms 2.1x6x3-4.5 were discovered,
as well as the surface of a yard. Its adobe walls
were preserved to a height of 22-43 cm. In rooms four
and five; a system of internal heating similar to
the Chinese khans was found. In the upper layers of
room five, an unknown copper coin with the Khorezm
stamp from the fourteenth century was found as well
as a Jagataid copper coin from the second half of
the eighth century. In the southeastern corner of
the excavation the remains of a potter's kiln were
also found.
The eighth stratum revealed the ruins of the walls
of two rooms and a well. The walls of the rooms were
built from burnt bricks of 27-28x25-29-4-5 cm in size
and preserved to a height of 37 cm and a thickness
of 72 cm. The upper part of the well was built with
burnt brick 24-28x25-30x3-5 cm. The well was filled
with rubbish containing pieces of ceramic from the
fourteenth — sixteenth centuries. In section
?/13 of the excavation, Q.A. Fyodrov-Davydov discovered
silver coins with the Khorezm stamp from 1500/1501.
The ninth stratum was separated from the lower layers
by rubble 1.1-1.2 m thick. Four rooms and the surface
of a big yard can be observed. Various materials were
found there, from pieces of ancient ceramics to ceramics
and bricks from the nineteenth century. According
to the excavation data the fortress walls of Ichan-kala
were restored during this period. Towers intended
for straight and flanking rifle fire strengthened
the walls.
In the tenth stratum, the walls, 7-9 m. in height,
1.5-2 m. thick and built from mud, were strengthened
by tall oval towers with battlements on top. The inside
housings had been strengthened with wooden beams.
Preserved coins from the time of Emperor Paul I (1801)
and pieces of china cups with the markings of the
Gardner and Kuznetzov plants were found within the
fortress wall. In the northwestern corner of excavation
no. 2 (10x14 m.), fire-building foundations were discovered.
Excavation ? 2. The first stratum: In the northern
section of the excavation only, a 3-9 m. thick sub-soil
cultural layer was discovered. According to the building
plan there was a square tower 11.5x11.5 m. in size.
The size of the house in the tower was 2.35x2.9x2.2
m. It was built with pieces of raw brick and the seams
were filled with large-grain sand. Ceramic material
belonging to the first horizon was discovered in the
deposited layer. An additional wall of about one meter
in thickness and preserved to a height of 0.75-0.88
m. stretched along the western facade of the fortress
wall, parallel to the main wall. The width of the
space between the fortress and the additional wall
covered by a layer of sand was 3.4-4 m.
The second stratum. The wall of the lower stratum
was built with raw bricks to a thickness of 1.8-1.9
m. The inside of the tower chamber was built in the
same way.
The third, fourth, fifth, and sixth strata were not
found, although pieces of ceramic from the seventh
— eighth and twelfth — thirteenth centuries
A.D. were found.
The seventh stratum revealed the remains of domestic
hearths. In the southern section of the excavation
the living area and a hearth with a diameter of 49
cm. was discovered. Pieces of gray ceramic and animal
bones, 9-1 1 cm thick, were seen in the ash and humus
layer. Grain pits were cut into the ancient wall of
the fortress. A porridge bowl from the thirteenth
— fourteenth centuries and pieces of pottery
and grain grinders were extracted from it.
The eighth stratum was not found.
The ninth stratum. The abode and raw walls of the
fortress were preserved to a height of 5-6 m. Nineteenth
century walls covered them. The cultural stratum of
0.27-0.43 in thickness contained pieces of ceramic
and animal bones. The tenth stratum. The walls of
Ichan-kala were built from abode 7-9 m. in height
on both sides. In the eastern sector of the excavation
was a dwelling area. Ceramics from the eighteenth
— nineteenth centuries 0.82-1.1 m in thickness
were discovered in the cultural layer.
Excavation ? 3, covering an area of 5x37 m., was done
in the southeastern corner of Ichan-kala.
The first stratum. As in the case of excavations ?l
and ?2, the foundation of the wall and towers of this
ancient period was also discovered. Towers were rectangular
(5.5x7.3 m.) in shape. The lower part made of mud
1.1-1.2m., in height, stood on sandy soil. There was
also a deep layer of raw brick (41-44x40-45x10-14
cm). The rooms (3x2.3 m.) in the tower on the foundational
level were built from raw brick and filled with sand.
A piece from a jug from the middle of the first millennium
B.C. was discovered here. The fortress walls in the
southeastern corner were uncovered for a length of
eight meters.
The second stratum was 13-22 cm thick. The thickness
of the outside walls was increased by 0.75-1.25 m.
to a total thickness of 3 m. The portion of the wall
that was added was 0.65 m. higher than the foundation.
The third stratum featured ruins of the wall, made
from raw brick 36-39x37-39x7-9 cm thick and 0.42 cm
in height. A square castle (1 1.5x 1 1.5 m) covers
the ruins of the earliest buildings erected in the
southeastern corner of Ichan-kala during that period.
The fourth stratum was not discovered.
The fifth and sixth strata are revealed several Muslim
burial mounds.
The seventh and eighth strata could not be found.
The ninth strata included hearth remains.
The tenth strata. The old walls of the fortification
were replaced with new abode walls on both sides.
A gallery 2-3 m. wide with a parapet across the front
2.5-3 m. high, with battlements and narrow slits was
erected on the fortress wall.
Excavation ?4, covering an area of 136 sq. m. was
done in the northeastern corner of Ichan-kala. The
fortress walls and towers belonged to the first strata.
The walls were built from raw square bricks. An outside
fortress wall, 7 m. long, 2 m. thick and 2.5 m. high,
was uncovered here. The thickness of the tower walls
was 2.61-2.75 m. and the width of the passage between
them was 0.8 m. The inside floor level of the tower
house was filled with large-grained gray sand which
was covered with a number of raw bricks with marks.
Uncovered on the floor of the house were pieces of
a red clay handle of a jug in the form of a lion's
head.
The second stratum. The inside tower houses were built
from raw bricks and the level of the floor rose to
2.4 m. The outer sidewalls of the tower were built
with raw bricks on one level to a thickness of 2-3.5
m. Thus, the lower section of the wall had been widened
as a result of which the inner-wall corridor was raised.
It was later found that during the erection of the
wall in the seventeenth century, all the preserved
remains of the building were pulled down. The seventeenth
— nineteenth century cultural layers of the
excavation appeared to be eroded and it was difficult
to sort the strata. However pieces of the walls and
vessels of the tenth-fourteenth centuries were found
in light green condensation.
The ninth stratum. The ancient walls are filled with
gray lumps of clay. A new defensive wall had been
erected with oval towers protruding beyond the fortress
wall by 6-8 m. A room found here was 3x4 m. The walls
were built from burnt bricks of 23-28x23-29x3-4.5
cm. The floor of the house was coated with straw and
clay. In the southwestern corner, there was a deep
pit in the floor with a diameter of 28 cm. The sidewalls
were built with half-burnt bricks.
The tenth stratum. The walls and the towers of the
city were built with abode consisting of lumpy clay
and in some places of whole and broken raw bricks.
The thickness was 1.5-2m.
Excavation ?5 (9x10 m.) was made at the foot of the
southern wall, 30 m. to the west of Tash-darbasa.
In the first stratum, pieces of ceramic were found
all over the area of the excavation. It was apparent
the strata were difficult to determine. Data from
the Kushan, Afrigid, that everything had been pulled
down to foundational level. Because of repeated excavations
Khorezmshah, and Golden Horde periods were found.
It is therefore possible to speculate that these levels
were completely destroyed while reconstructing houses,
some time in the thirteenth — nineteenth centuries.
Excavation ?6, covering an area of 60 sq. m. was carried
out at the foot of the western wall for a distance
of 105 m. to the north from the south-western corner
of Ichan-kala. It was discovered that the lower section
of an earthen wall consisted of the remains of the
two walls from excavation ?5. The ruins of a rectangular
tower were found, 7 m. wide, preventing approach to
the western part of the town. According to the excavation
materials it is clear that sand was widely used.
From archaeological research, historians have been
able to more clearly delineate and describe the distinct
periods in the history of Khiva. The first two periods
witnessed its settlement and fortification (sixth
— third centuries, B.C.) and the first flourishing
of its life, reaching into the present millennium.
Then, at the end of the fourth century, the town's
fortifications were weakened. The same thing was observed
on the site of the ancient towns of Burla-Kala, Tok-Kala
and Koi-Krilgan-kala. The decline and gradual dying
away of life in the towns of Khorezm at the end of
the fourth century represented a crisis for ancient
Khorezm.
Archaeological studies identified a period of revival
around the sixth — eighth centuries. Keshks
(castles) began to appear in the region of Khiva.
Buildings of this type were very famous in the settled
and agricultural regions of Khorezm. The ruins of
this type of castle can be seen on Akshikh-bobo hill
near Kunya-Ark. The same type of rectangular castle
is located in the southeastern corner of Ichan-kala.
The ruins of the castle consist of solid abode, 6-7
m. in height, in the form of a truncated pyramid.
The building was probably used for defensive purposes,
but during peacetime it was used for storing provisions
and other household goods since millstones made of
sand, the remainders of grain (millet) and straw were
found in the construction and on the plinth. From
layers corresponding to these buildings, examples
of various ceramics were taken — pieces of thick
clay pots, pieces from water jugs with a flat narrow
handle, and other artifacts from the Afrigid period.
The prevalence of Zoroastrian notions during this
period is borne out by the pieces of ceramic. The
development of monetary relations is shown by silver
coins- from the period of the reign of shahs Bravik
and Shaushfan during the seventh — eighth centuries.
The absence of information about Khiva for the eighth
century was probably the result of the ruthless destruction
of cities and cultural monuments of Khorezm during
the Kutaib b. Muslim's campaign to conquer Khorezm.
In the tenth century, Khiva, was incorporated into
the Samanid Empire, and became part of the domain
of Khorezmshah Mamnun. Mukhammed in 995. The dynasty
of Mamnu-ids ruled Khorezm until 1017, when the Qhaznevids,
who reigned from 1017 to 1034, conquered it.
This time was marked by the revival of Khiva —
the rapid development of the city, its economy, craft
and culture. Traces of this time were discovered in
all the excavations and proved the considerable growth
of Khiva, covering the whole Ichan-kala region and
probably Dishan-kala as well. A manufacturing industry
for glass, metal and ceramics developed. The Khiva
potters were real masters as they made light, elegant
ceramic vessels with extraordinary patterns. The vessels
were covered with various rosettes, stylized leaves
and shoots, and sometimes with portrayals of animals,
birds and fish; Arabian script was often used in the
decorations, wishing the owner well with moral proverbs
and sayings.
According to Istarkhi (tenth century), Khiva was situated
a day's ride from Khazarasp and the ancient capital
of Khorezm — Kyat, and a four-day's ride from
the capital city of that time, Qurgani. Many ariks
and canals, the biggest of which was Khiva, the future
Palvan-yab, irrigated the lands of Southern Khorezm.
According to Mukaddasi (975), «Khiva is a huge
walled city situated on the edge of the desert next
to a canal. There is a modern mosque with all the
necessary amenities». At the same time, according
to an anonymous geographical work from the tenth century
called Khudud al-Alam, «Khiva is a small city,
surrounded by a wall and belongs to Urgench».
Q.A.Pugachenkova reconciled this seeming contradiction
by positing that Muqaddas meant all of Khiva —
including Ichan-kala and Dishan-kala — while
the author of Khud al-Alam included Ichan-kala only.
Thus, during the second half of the tenth century,
Khiva apparently consisted of a citadel, fortified
by the walls of Shakhristan (Ichan-kala) and an outlying
settlement (Dishan-kala).
The end of the eleventh century marked a new period
in the history of Khorezm. In 1077 it was taken over
by the Anushteginid dynasty, which established a large
Muslim state under Khorezmshahs Ala ad-Din Tekesh
(1172-1 200) and Ala ad-Din Mukhammed (1200-1220).
At this time the city started to flourish anew. Amongst
the ruins are the coins of Khorezmshahs Tekesh and
Mukhammed, pieces of gray ceramics: large clay pots,
small clay pots, jugs, bowls, pots, and irrigation
ceramics. The city began to spread and new settlements
outside Ichan-kala began to appear. Many materials
of the Khorezmshah period were found on the Sha-Qalandar-bobo
site and in the area of hotel Khorezm. The settlement
of Shah-i-Mardon appeared to the west, and the materials
of its houses have found in the excavations.
A geographical dictionary by Yakut contains information
about Khiva for the first half of the thirteenth century:
«Kheivyak or Khivak is a fortress city in the
region of Khorezm. The distance between Khiva and
the capital of Khorezm (Urgench) is about 105 km.
The inhabitants of Khorezm call it Khiva. According
to Misba it is Khivaki. The inhabitants of this city
are shafiits, in contrast to those of all the rest
of the cities of Khorezm, whose inhabitants are called
khanifits».
There were a few famous Khivans in this period. One
of them was Shihab ad-din Abu Sa'd b. Imran al-Khivaki,
a jurist, mufti of the ash-Shafi school, a scholar,
and an outstanding public figure of the Khorezmshah
state. He created a library in Urgench «the
likes of which had not been seen before or after.»
The Mongols executed Shihab ad-Din Al Khivaki when
they seized the city of Flisa; he was buried there
in the sepulcher of Ali Jafta.
The famous Sufi, sheikh, imam, and founder of the
Order of al-Kubraviya, Abu-1 Jannab Ahmad b. Umar
Mukhammed al-Khivaki (better known as Hajim ad-Din
Kubra, 1145-1221), died during the capture of Khorezm
by the Mongols. A mausoleum in honor of Majim ad-Din
Kubra is in Kunya-Urgench.
At the beginning of the thirteenth century, Khiva
was almost completely destroyed during the Mongol
invasion, as were the other cities and towns of Khorezm.
Although there are no references to it in written
sources, the fortress wall of Ichan-kala was destroyed,
and it was turned into a burial place.
According to the author of Iskandar's Anonyma, Chinghiz-khan
gave Khiva to Chigatay and the rest of Khorezm to
Juchi, who recorded that 'Amir Khusain Sufi, amir
Budagay's son collected taxes from Kyat and Khiva
unjustly; they belonged to Chighatay's sultans in
ancient times». In the 1360s through 1380s,
Khiva belonged to the Kungrad Sufis, until Amir Temur
ended their reign.
Muhammad-Amin the inak ruled over them. Me began ruling
the state on behalf of the king's son, Chinghizids,
who gradually lost his influence. At Mukhammad Amin
inak's initiative, puppet khans were enthroned and
dethroned in majority of cases they were brought from
the steppe. The eye-specialist, Blankennagel, who
came to Khiva to treat a blind Khiva khan (the treatment
was not successful) noted that a puppet khan showed
himself to the people only three times a year, and
the rest of time he was kept locked away, suffering
deprivation of the most necessary things. Yakov Petrov
reported the same thing from Orenburg, who served
as a slave in Bukhara and Khiva from 1787 to 1819:
The khan has only the name of Khan. He is not allowed
to take up his duty.
The grandson of Mukhammad Amin inak, Eltuzar (1804-1806),
officially accepted the title of khan in 1804 and
became the ancestor to the Kungrad dynasty (1763-1920),
a dynasty that ruled the Khiva Khanate until 1920.
Mukhammad Amin inak led a successful fight against
the rulers of small independent territories. Me promoted
the union of dispersed regions into one state with
a capital in Khiva. Mukhammad Amin inak efficiently
used Turkmen tribe leaders of yomuts and choudors
in his policy. Me led them to Khiva, gave them privileges,
and later dealt with them brutally.
The dynastic struggle and feudal wars affected the
life of people in Khiva. Many of them had to leave
the city. Mukhammad Amin, after defeating his enemies,
began strengthening the country. «The state
was put into order, and the population began living
quietly» under his reign, noted the Firdaus
alkbal, «At that time starvation was done away
with, the time of low prices came, and one could buy
one grown sheep for two yarmaks, and for a dinar one
could buy forty batmuns of wheat or sixty batmuns
of corn by the Khiva weight». Under his reign
many things had been done concerning irrigation. It
contributed to the promotion of agriculture and to
the settling of nomads and semi-nomads. By order of
Mukhammad Amin inak many dilapidated buildings were
repaired, and the destroyed city walls of Khiva were
reconstructed.
Under Mukhammad Rahim (1806-1825) a further unification
of isolated, half-independent principalities into
one united state took place. The domestic affairs
were also more closely regulated under him. Mukhammad
Rakhim organized and headed Supreme Council to discuss
important state issues. It consisted of higher dignitaries
and representatives of the Uzbek tribes. Mukhammad
Rakhim carried out a tax reform and introduced customhouses.
Under him gold and silver coins were minted, which
contributed to the widening of economic relations
between Khiva and other regions. Under Mukhammad Rakhim's
son, Alia-Kuli-khan, the Khiva Khanate widened its
limits considerably.
