Start End Reign 1849 AD 1850 AD 

　　Zachary Taylor (November 24, 1784 – July 9, 1850) was an American military leader and the 12th President of the United States.
　　
　　Known as "Old Rough and Ready," Taylor had a 40-year military career in the U.S. Army, serving in the War of 1812, Black Hawk War, and Second Seminole War before achieving fame leading U.S. troops to victory at several critical battles of the Mexican–American War. A Southern slaveholder who opposed the spread of slavery to the territories, he was uninterested in politics but was recruited by the Whig Party as their nominee in the 1848 presidential election.
　　
　　In the election, Taylor defeated the Democratic nominee, Lewis Cass, and became the first U.S. president never to have held any previous elected office. Taylor was also the last southerner to be elected president until Woodrow Wilson. As president, Taylor urged settlers in New Mexico and California to bypass the territorial stage and draft constitutions for statehood, setting the stage for the Compromise of 1850.
　　
　　Taylor died of acute gastroenteritis just 16 months into his term. He was succeeded by the then Vice President Millard Fillmore.
