Throughout the 19th century, Boston became a haven for Irish Catholic immigrants, especially following the Great Famine of the late 1840s. Their arrival transformed Boston from a singular, Anglo-Saxon, Protestant city to one that has progressively become more diverse. The Yankees hired Irish as workers and servants, but there was little social interaction. In the 1850s, an anti-Catholic, anti-immigrant movement was directed against the Irish, called the Know Nothing Party. But in the 1860s, many Irish immigrants joined the Union ranks to fight in the American Civil War, and that display of patriotism and valor began to soften the harsh sentiments of Yankees about the Irish. Nonetheless, as in New York City, on July 14, 1863, a draft riot attempting to raid Union armories broke out among Irish Catholics in the North End, resulting in approximately 8 to 14 deaths. In the 1860 presidential election, Abraham Lincoln received only 9,727 votes out of 20,371 cast in Boston (or 48 percent) while receiving 63 percent of the vote statewide, and Boston Irish Catholics mostly voted against Lincoln.
