William Henry Harrison (1773 – 1841) was the ninth president of the United States (1841) and the first president to die in office. Harrison died on his 32nd day in office of complications from pneumonia, serving the shortest tenure in United States presidential history. He was 68 years old when inaugurated, the oldest president to take office until Ronald Reagan in 1981. He was born into a prominent political family in Virginia, who owned plantations and slaves. Before election as president, he gained national fame for leading U.S. military campaigns against native Americans. As governor of the Indiana territory, he supervised the development of 13 treaties, which resulted in native Americans losing 60 million acres of their tribal land. He was hailed by many as a national hero. His political party was "Whig."
