Question: Question: What main language was spoken by the tribe of which Khalid was a member? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Question: Question: Did Sparta exist beyond 371? Passage:The scale and scope of warfare in Ancient Greece changed dramatically as a result of the Greco-Persian Wars, which marked the beginning of Classical Greece (480-323 BC). To fight the enormous armies of the Achaemenid Empire was effectively beyond the capabilities of a single city-state. The eventual triumph of the Greeks was achieved by alliances of many city-states, on a scale never seen before. The rise of Athens and Sparta during this conflict led directly to the Peloponnesian War, which saw diversification of warfare. Emphasis shifted to naval battles and strategies of attrition such as blockades and sieges. Following the defeat of the Athenians in 404 BC, and the disbandment of the Athenian-dominated Delian League, Ancient Greece fell under the Spartan hegemony. But this was unstable, and the Persian Empire sponsored a rebellion by the combined powers of Athens, Thebes, Corinth and Argos, resulting in the Corinthian War (395-387 BC). Persia switched sides, which ended the war, in return for the cities of Ionia and Spartan non-interference in Asia Minor. The Spartan hegemony would last another 16 years, until, at the Battle of Leuctra (371) the Spartans were decisively defeated by the Theban general Epaminondas.


Answer: The Spartan hegemony would last another 16 years, until, at the Battle of Leuctra (371) the Spartans were decisively defeated by the Theban general Epaminondas


Question: Question: When was the person to whom Ji was a subordinate born? Passage:Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors – Cao Pi, Cao Rui and Cao Fang – and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'état against his co-regent Cao Shuang, but died from illness a few months later.
