PROBLEM: Why did the Ottonian dynasty get replaced by the Salian dynasty?, Context: During the early High Middle Ages, Germany was ruled by the Ottonian dynasty, which struggled to control the powerful dukes ruling over territorial duchies tracing back to the Migration period. In 1024, they were replaced by the Salian dynasty, who famously clashed with the papacy under Emperor Henry IV (r. 10841105) over church appointments as part of the Investiture Controversy. His successors continued to struggle against the papacy as well as the German nobility. A period of instability followed the death of Emperor Henry V (r. 111125), who died without heirs, until Frederick I Barbarossa (r. 115590) took the imperial throne. Although he ruled effectively, the basic problems remained, and his successors continued to struggle into the 13th century. Barbarossa's grandson Frederick II (r. 12201250), who was also heir to the throne of Sicily through his mother, clashed repeatedly with the papacy. His court was famous for its scholars and he was often accused of heresy. He and his successors faced many difficulties, including the invasion of the Mongols into Europe in the mid-13th century. Mongols first shattered the Kievan Rus' principalities and then invaded Eastern Europe in 1241, 1259, and 1287.

SOLUTION: struggled to control the powerful dukes ruling over territorial duchies

PROBLEM: At what point did Florida finally have fairly drawn congressional districts?, Context: Reapportionment following the 2010 United States Census gave the state two more seats in the House of Representatives. The legislature's redistricting, announced in 2012, was quickly challenged in court, on the grounds that it had unfairly benefited Republican interests. In 2015, the Florida Supreme Court ruled on appeal that the congressional districts had to be redrawn because of the legislature's violation of the Fair District Amendments to the state constitution passed in 2010; it accepted a new map in early December 2015.

SOLUTION:
December 2015
