美國嚮西擴展  (1773年二月9日～1841年四月4日)

開端 終結 在位 1841年 1841年 

　　威廉·亨利·哈裏森（1773年2月9日－1841年4月4日），是美國的第9任總統(1841年3月4日 – 1841年4月4日)，軍事傢，曾在與印第安人的戰鬥中獲得勝利。他在1841年死在任內。
　　
　　哈裏森上任的那天很冷。他的上任演講是美國歷史上最長的，將近兩個鐘頭。他沒有穿大衣在外面演講，得了急性肺炎，31天之後病逝，成為美國歷史上第一個在任內逝世的總統，也是美國歷史任期最短的總統。他去世之後，美國輝格黨開始衰敗。
　　
　　他的孫子，本傑明·哈裏森，是美國第23任總統。

　　William Henry Harrison (February 9, 1773 – April 4, 1841) was the ninth President of the United States, an American military officer and politician, and the first president to die in office. The oldest president elected until Ronald Reagan in 1980, and last President to be born prior to the United States Declaration of Independence, Harrison died on his 32nd day in office—the shortest tenure in United States presidential history. His death sparked a brief constitutional crisis, but that crisis ultimately resolved many questions about presidential succession left unanswered by the Constitution until passage of the 25th Amendment.
　　
　　Before election as president, Harrison served as the first territorial congressional delegate from the Northwest Territory, governor of the Indiana Territory and later as a U.S. representative and senator from Ohio. He originally gained national fame for leading U.S. forces against American Indians at the Battle of Tippecanoe in 1811, where he earned the nickname "Tippecanoe" (or "Old Tippecanoe"). As a general in the subsequent War of 1812, his most notable contribution was a victory at the Battle of the Thames in 1813, which brought an end to hostilities in his region.
　　
　　After the war, Harrison moved to Ohio, where he was elected to the United States Congress, and in 1824 he became a member of the Senate. There he served a truncated term before being appointed as Minister Plenipotentiary to Colombia in May 1828. In Colombia, he lectured Simon Bolívar on the finer points of democracy before returning to his farm in Ohio, where he lived in relative retirement until he was nominated for the presidency in 1836. Defeated, he retired again to his farm before being elected president in 1840.
