Zachary Taylor (November 24, 1784 – July 9, 1850) was the 12th president of the United States, serving from March 1849 until his death in July 1850. Taylor was born into a prominent family of plantation owners who moved westward from Virginia to Louisville, Kentucky in his youth. 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 establishing military forts along the Mississippi River and entered the Black Hawk War as a colonel in 1832. He did not favor chartering another national bank, favored a low tariff, and believed that the president should play no role in making laws. Taylor did believe that the president could veto laws, but only when they were clearly unconstitutional. Many southerners believed that Taylor supported slavery and its expansion into the new territory absorbed from Mexico, and some were angered when Taylor suggested that if he were elected president he would not veto the Wilmot Proviso, which proposed against such an expansion.
