How was the U. S. involved in Mexico before and during the Mexican Revolution in 1910?

An increasing number of border incidents early in 1916 culminated in an invasion of American territory on 8 March 1916, when Francisco (Pancho) Villa and his band of 500 to 1,000 men raided Columbus, New Mexico, burning army barracks and robbing stores. In the United States, Villa came to represent mindless violence and banditry.
