Question: Who was governor of the state in which Moore studied law in 1856? Passage:He was born in Lewisburg, Virginia in a portion of the state along the Ohio River which became West Virginia in his lifetime. His father had been born in Shenandoah County and moved across the Appalachian Mountains to the Greenbrier County area, but died when Charles was an infant. His paternal grandfather had married a daughter of Joseph Morgan, who helped settle the trans-Appalachian area. His mother, Augusta Delphia Page of Staunton, Virginia, a daughter of Major Charles Page, died in 1844 so Charles and his sister were raised by their uncle, George Moore in Mason County. When Charles was 16, he was sent to Marshall Academy in Huntington, and he would also study with John I Van Meter in Pike County, Pennsylvania, then attend Jefferson College (which later became Washington and Jefferson College) in Canonsburg, Pennsylvania. While at Jefferson College, Charles Moore helped found the Phi Kappa Psi fraternity before graduating in 1853. Moore then briefly attended Union College in New York. Returning to Virginia, he studied law at the University of Virginia and completed the course in 1856.

Question: How long did it take Timur to take over Tbilisi? Passage:Timur's first appearance in the Caucasus was a response to Khan Tokhtamysh's marauding inroad into Northern Iran through the Caucasian lands in 1385. This marked an outbreak of outright hostility between the two Islamic monarchs. Timur responded by launching a full-scale invasion of the small frontier countries, which lay between the western border of his emerging empire and Tokhtamysh's khanate. After having overrun Azerbaijan and Kars, Timur marched into Georgia. The official history of his reign, Zafarnama, represents this campaign in Georgia as a jihad. Timur set out from Kars and assailed Samtskhe, the southernmost principality within the Kingdom of Georgia later in 1386. From there, he marched against Tbilisi which the Georgian king Bagrat V had fortified. The city fell on November 21, 1386, and King Bagrat V was captured and converted to Islam at sword point. The Georgian Chronicle and Thomas of Metsoph mention the apostasy of the king but represent it as a clever ruse which enabled him to earn a degree of trust of Timur. Bagrat was given some 12,000 troops to reestablish himself in Georgia whose government was run by Bagrat's son and co-ruler George VII during his father's absence at Timur's court. The old king, however, entered in secret negotiations with George who ambushed Bagrat's Islamic escort, and freed his father.
