Problem: The Houston Texans joined the league at the 2002 NFL season, playing at the newly founded Reliant Stadium.  With their opening game victory over the Dallas Cowboys that season, the team became the first expansion team to win its opening game since the Minnesota Vikings beat the Chicago Bears in 1961.  While the team struggled in early seasons, results began to improve once native Houstonian Gary Kubiak became the head coach in 2006. The Texans finished with a .500 season (8-8) in both 2007 and 2008, and nearly qualified for the 2009-10 NFL playoffs with a 9-7 result in 2009. In 2010, the team started the season on a 4-2 record going into a Week 7 bye week, but promptly collapsed 2-8 in the second part of the season, finishing 6-10. In the 2011 NFL Draft, the Texans acquired Wisconsin Badgers football star defensive end J.J. Watt eleventh overall. The following season, former Dallas Cowboys head coach Wade Phillips was hired as the defensive coordinator of the Texans, and the improved defense led to the Texans finishing 10-6, winning their first AFC South title. The Texans then beat wild card Cincinnati Bengals 31-10 in the first round of the 2011-12 NFL playoffs, before a 20-13 defeat by the Ravens in the semifinals.

Problem: 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 June  1864. 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.
