PROBLEM: Question: How long had Ferdinand I been in power the year Coimbra fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.

PROBLEM: Question: Which tribe was Chief Blackfish the Chief of? Passage:Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.
