Yuli is said in the Hanshu or 'History of the Former Han' (covering the period 125 BCE to 23 CE), to have had 1,200 households, 9,600 individuals and 2,000 people able to bear arms.

[13] In 61 CE, the Xiongnu led some 30,000 troops from 15 kingdoms including Korla, Karashahr, and Kucha in a successful attack on Khotan.

In 94 CE, the Chinese general Ban Chao sent soldiers to punish the kingdoms of Yanqi (Karashahr), Weixu (Hoxud), Yuli (Korla), and Shanguo (in the western Kuruk mountains).

[20] On January 8, 1965, more than 170 Chinese Communist cadres were immolated by Mongols during an anti-Communist riot at a state farm in Korla (Kurla).

[23] Korla is approximately 200 kilometres (120 mi) southwest from Ürümqi, although, due to the intervening Tian Shan, the road distance is considerably greater.

The monthly 24-hour average temperature ranges from −6.6 °C (20.1 °F) in January to 26.8 °C (80.2 °F), and the annual mean is 12.0 °C (53.6 °F), which is still warmer than most locales at the same latitude further east in the country.

The period between April and October closely resembles subtropical climates, but the continental nature is facilitated by the rapid drop of temperatures going into winter.

[20] The city had 430,000 inhabitants in 2007, increasing with 20,000 people every year, majority of whom were Han Chinese, with a large minority of Uyghurs (about 100,000) and smaller numbers of Mongols and Huis.

[citation needed] Korla has long been the biggest centre in the region after Karashahr/Yanqi itself, having abundant water and extensive farmlands, as well as controlling the main routes to the south and west of Karashahr/Yanqi.
