The name Khorezm appears in the Avesto, a Zaroastrian religious text, which illustrates the course of events in Eastern Iran and Central Asia, during which time the society comprised of different classes of economic disparity. Avesto informs the functions of clergies, army, farmers, craftsmen, and slaves altogether which formed the first statehood. The events in Avesto occurred in a land “Arianam Vayja” as the translation confirmed by scientists as Great Khorezm.
This empire included Praurata (Parfiya), Mouru (Marv), Gava (Sagdiana), and Khveyrezm (Khorezm).
So, the first statehood developed in Central Asia in the first millennium B.C. Bactria in the IX- VIII century B.C and in the lower reaches, south of the Aral sea (Northwest of Uzbekistan, North west of Turkmanistan). Khorezm developed in the VI-V century B.C. as kingdoms. Bactria and Khorezm shared frontiers in the middle Amudarya river delta. The first artificial irrigation construction in Khorezm dates back to the VI-V century B.C. Population was mainly occupied with agriculture in the villages, and craftsmanship and trade in urban areas.
The archeological excavation confirms that Khorezmians were not only occupied with trade and agriculture but also with science. Khorezmians had sophisticated knowledge of astronomy and mathematics. They invented angle measuring equipments and used them in their scientific researches. Astronomic and many natural sciences developed in ancient Khorezm. The constructions of such equipment survived until this day. One of these constructions and cultural heritage of Khorezm is Koykyrilgan Kala. It’s located few kilometers north of the Amudaryariver. The construction dates back to the IV century B.C. The fortress functioned as a burial-ground for the rulers as well as observatory for astronomic studies. During the excavation the archeologists found another interesting document that supposed to be the calendar of Khorezmians dating back to the III century A.D.
The Khorezmians, for instance, based their prosperity exclusively on their trade with the Turks, and became chief representatives of the merchant class throughout the country, especially in Khorasan. They could be found in considerable numbers in every city of Khorasan, distinguishable from the local inhabitants by the high fur caps which are worn in present-day Khorezm. The development of material prosperity was accompanied, not coincidentally, by that of intellectual pursuits. Almost every teacher at that time could number some Khorzmians among his disciples. This stands in direct relation to the high level of learning in Khorezm itself, particularly in Kath and Guganj, at the end of the tenth and beginning of the eleventh centuries.
Khorezm was one of most important lands in Central Asia with its commercial, political, and cultural development from the VI century B.C until the XIX century A.D. Thanks Khorezm’s strategic location on the Great Silk road from Iran to India, it actively participated in fostering relations among various cultures and kingdoms. Therefore traders, craftsmen, scientists and architects visited here as an important destination. So the Great Silk Road was not merely a caravan trade route but it also played an instrumental role in the development of civilization of Central Asia.
