Archaeology of Uzbekistan

Kangju (; Eastern Han Chinese: kʰɑŋ-kɨɑ < *khâŋ-ka (c. 140 BCE)) was the Chinese name of a kingdom in Central Asia during the first half of the first millennium CE. The name Kangju is now generally regarded as a variant or mutated form of the name Sogdiana. According to contemporaneous Chinese sources, Kangju was the second most powerful state in Transoxiana, after the Yuezhi. Its people, known in Chinese as the Kāng (康), were evidently of Indo-European origins, spoke an Eastern Iranian language, and had a semi-nomadic way of life. The Sogdians may have been the same people as those of Kangju

Kyzyl-Kala, also Qyzyl Qala ("Red fortress"), in modern Karakalpakstan, Uzbekistan, was an ancient fortress in Chorasmia built in the 1st-4th century CE. The small fortress of Kyzyl-Kala is located near Toprak-Kala, about 1 km to the west, and was also built in the 1st-4th century CE, possibly as a fortified defense for the site of Toprak-Kala. Kyzyl-Kala was once restored in the 12th century. It has also been the subject of a modern renovation program, with the objective of showing what a fortress looked like originally. It is part of the "Fifty fortresses oasis" in modern-day Uzbekistan. It
