Starting the Mexican-American War

On March 4, 1849, Zachary Taylor was sworn in as the 12th President of the US.  He was the last North American President to own African-American slaves while in office.  Earlier, under orders of the previous President James Polk, Taylor positioned US troops on Mexican territory to provoke the Mexicans into war (which would be known in the 21st century as “meddling” in Mexican elections). Taylor and Polk soon succeeded in their Grand Theft, and the Mexican-American war began in 1846.
