Taylor was a career officer in the United States Army, rising to the rank of major general and becoming a national hero for his victories in the Mexican–American War. As a result, he won election to the White House despite his vague political beliefs. His top priority as president was to preserve the Union. He died 16 months into his term from a stomach disease, thus having the third shortest presidency in U.S. history.
Taylor was born into a prominent family of plantation owners who moved westward from Virginia to Louisville, Kentucky, in his youth; he was the last president born before the adoption of the Constitution. He was commissioned as an officer in the U.S. Army in 1808 and made a name for himself as a captain in the War of 1812. He climbed the ranks of the military, establishing military forts along the Mississippi River and entering the Black Hawk War as a colonel in 1832. His success in the Second Seminole War attracted national attention and earned him the nickname "Old Rough and Ready".
