question:
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?

question:
Passage: When Sigurd died in 1130, Harald broke his oath. Sigurd's son Magnus was proclaimed king, but Harald also claimed the royal title, and received much support. A settlement was reached whereby Magnus and Harald would both be kings and co-rulers. Peace between them lasted until 1134, when open war broke out. In 1135 Harald succeeded in defeating and capturing Magnus in Bergen. Magnus was blinded, castrated, mutilated and imprisoned in a monastery. He was thereafter known as Magnus the Blind. At about the same time Sigurd Slembe, another man from Iceland, arrived claiming to be a son of Magnus Barefoot. He claimed to have gone through an ordeal by fire in Denmark to prove his claim. Harald did not recognize him as his half-brother. In 1136 Sigurd murdered Harald in his sleep in Bergen, and had himself proclaimed king. Harald's supporters would not accept him and had Harald's two infant sons, Sigurd Munn and Inge Crouchback, named king. Sigurd Slembe liberated Magnus the Blind from his enforced monastic life and allied himself with him. The war between Sigurd Slembe and Magnus the Blind on the one side, and Harald Gille's old supporters with his young sons on the other, dragged on until 1139, when Magnus and Sigurd were defeated in Battle of Holmengrå fought near Hvaler. Magnus was killed in the battle, Sigurd was captured and tortured to death.
