History: American Old West, United States

• Border War
In 1910 the last conflict of the Old West began when Mexican Carrancistas rebelled against their government. Fighting spread all across Mexico and along the Mexican-American border, several battles were fought between American soldiers and citizens against Mexicans. On many different occasions Mexican bandits crossed the border and raided American settlements. Also, thousands of Americans joined the rebellion in Mexico and fought at all of the major engagements in the north including the Battle of Ciudad Juarez in 1911 and the Siege of Naco in 1914. In 1916 an army of American cavalry invaded Mexico as part of the Punitive Expedition, an attempt to capture the famous border bandit and rebel Pancho Villa. By the end of the revolution the Old West era was coming to an end with the rise of modern society in the region.
