Passage: The Russo-Circassian War  involved a series of battles and wars in Circassia, the northwestern part of the Caucasus, in the course of the Russian Empire's conquest of the Caucasus. Fighting lasted approximately 101 years, starting in the reign of Empress Catherine the Great and finishing in 1864. Although the Russian conquest of the Caucasus started at least as early as the Russo-Persian Wars, the term Caucasian War commonly refers only to the period 1817-1864. Those who use the term Russian-Circassian War take its starting date as 1763, when the Russians began establishing forts, including at Mozdok, to be used as springboards for conquest. The Caucasian War ended with the signing of loyalty oaths by Circassian leaders on 2 June  1864. Afterwards, the Ottoman Empire offered to harbour the Circassians who did not wish to accept the rule of a Christian monarch, and many emigrated to Anatolia, the heart of the Ottoman territory and ended up in modern Turkey, Syria, Jordan, Israel, Iraq and Kosovo. Different smaller numbers ended up in neighbouring Persia. Various Russian, Caucasus, and Western historians agree on the figure of ca. 500,000 inhabitants of the highland Caucasus being deported by Russia in the 1860s. A large fraction of them died in transit from disease. Some of those that remained loyal to Russia were settled into the lowlands, the left-bank of the Kuban River.
Question: How many years did the Caucasian War last?

Passage: In the 1650s, Burma became entangled in the dynastic changes in China. In 1651, Ming armies fleeing from the Qing forces entered Kengyun , which had paid tribute to both China and Burma. King Pindale sent five regiments to the front in October 1651. But the armies were driven back by the Ming in December 1651. Pindale would not contest again. In 1658, Zhu Youlang, one of the sons of the last Ming emperor, and his 700 followers were given permission to stay at Sagaing. In early 1659, other fleeing Ming armies entered the Shan states, and occupied Nyaungshwe and Mone with the intention to set up a kingdom for their emperor. For the next two years, the Ming forces proved a menace to Upper Burma. Not only Pindale could not drive out the Ming but it was the Ming that continually threatened the Burmese capital itself, and ransacked Upper Burma districts. On 4 June 1661, Pye Min overthrew his ineffectual brother, and took over the command. He finally drove out the Ming by November 1661. The problems were not yet over for the Burmese. On 21 December 1661, a Qing army of 20,000 under Gen. Wu Sangui showed up at Ava, demanding the surrender of the Ming emperor. The emperor was handed over on 15 January 1662, and the Qing forces left a week later.
