202 BC: Liu Bang, the founding emperor of the Han Dynasty, established Chang'an County as his capital; his first palace Changle Palace was built across the river from the ruin of the Qin capital. This is traditionally regarded as the founding date of Chang'an and Xi'an.

194 BC: Construction of the first city wall of Chang'an began, which did not finish until 190 BC. The wall measured 25.7 km in length, 12-16 m in thickness at the base. The area within the wall was ca. 36 km2.  Xian was the starting point of the ancient Silk Road. It was also among the richest cities in China because of the silk trades with the west.
190 BC:The most powerful tyrant of the time, Dong Zhuo, moves the court from Luoyang to Chang'an in a bid to avoid a coalition of powerful warlords against him.

582: Emperor of Sui Dynasty ordered a new capital to be built southeast of the Han capital, called Daxing (Great Excitement). It consisted of three sections: the X'ian Palace, the Imperial City, and the civilian section. The total area within the wall was 84 km2. The main street Zhuque Avenue measured 155 m in width. It was the largest city in the world.
