PROBLEM: Passage: The earliest human remains found on the island of Sri Lanka date to about 35,000 years ago . The proto-historical period begins roughly in the 3rd century, based on chronicles like the Mahavamsa, Dipavamsa, and the Culavamsa. The earliest documents of settlement in the Island are found in these chronicles. These chronicles cover the period since the establishment of the Kingdom of Tambapanni in the 6th century BCE. The first Sri Lankan ruler of the Anuradhapura Kingdom, Pandukabhaya, is recorded for the 4th century BCE. Buddhism was introduced in the 3rd century BCE by Arhath Mahinda . The first Tamil ruler of the Anuradhapura Kingdom, Ellalan, an invader, is recorded for the 2nd century BCE. The island was divided into numerous kingdoms over the following centuries, intermittently united under Chola rule. Sri Lanka was ruled by 181 monarchs from the Anuradhapura to Kandy periods.From the 16th century, some coastal areas of the country were also controlled by the Portuguese, Dutch and British.Between 1597 and 1658, a substantial part of the island was under Portuguese rule. The Portuguese lost their possessions in Ceylon due to Dutch intervention in the Eighty Years' War. Following the Kandyan Wars, the island was united under British rule in 1815.Armed uprisings against the British took place in the 1818 Uva Rebellion and the 1848 Matale Rebellion. Independence was finally granted in 1948 but the country remained a Dominion of the British Empire until 1972. In 1972 Sri Lanka assumed the status of a Republic. A constitution was introduced in 1978 which made the Executive President the head of state. The Sri Lankan Civil War began in 1983, including an armed youth uprising in 1971 and 1987-1989, with the 25-year-long civil war ending in 2009.

PROBLEM: 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 June1864. 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?

PROBLEM: Passage: The Livonian War was fought for control of Old Livonia , when the Tsardom of Russia faced a varying coalition of Denmark-Norway, the Kingdom of Sweden, and the Union of the Grand Duchy of Lithuania and the Kingdom of Poland. During the period 1558-1578, Russia dominated the region with early military successes at Dorpat and Narva. Russian dissolution of the Livonian Confederation brought Poland-Lithuania into the conflict, while Sweden and Denmark both intervened between 1559 and 1561. Swedish Estonia was established despite constant invasion from Russia, and Frederick II of Denmark bought the old Bishopric of Osel-Wiek, which he placed under the control of his brother Magnus of Holstein. Magnus attempted to expand his Livonian holdings to establish the Russian vassal state Kingdom of Livonia, which nominally existed until his defection in 1576. In 1576, Stefan Batory became King of Poland as well as Grand Duke of Lithuania and turned the tide of the war with his successes between 1578 and 1581, including the joint Swedish-Polish-Lithuanian offensive at the Battle of Wenden. This was followed by an extended campaign through Russia culminating in the long and difficult siege of Pskov. Under the 1582 Truce of Jam Zapolski, which ended the war between Russia and Poland-Lithuania, Russia lost all its former holdings in Livonia and Polotsk to Poland-Lithuania. The following year, Sweden and Russia signed the Truce of Plussa with Sweden gaining most of Ingria and northern Livonia while retaining the Duchy of Estonia.
