Overview
The Know Nothing movement was a nativist political movement in the United States in the mid-1850s. The national political organization of the Know Nothings was officially known as the "Native American Party" prior to 1855; thereafter, it was simply known as the "American Party". Members of the movement were required to say "I know nothing" whenever they were asked about its specifics by outsiders, providing the group with its colloquial name.
Supporters of the Know Nothing movement believed that an alleged "Romanist" conspiracy to subvert civil and religious liberty in the United States was being hatched by Catholics. Therefore, they sought to politically organize native-born Protestants in defense of their traditional religious and political values. The Know Nothing movement is remembered for this theme because Protestants feared that Catholic priests and bishops would control a large bloc of voters. In most places, the ideology and influence of the Know Nothing movement lasted only one or two years before it disintegrated due to weak and inexperienced local leaders, a lack of publicly proclaimed national leaders, and a deep split over the issue of slavery. In parts of the South, the party did not emphasize anti-Catholicism as frequently as it emphasized it in the North and it stressed a neutral position on slavery, but it became the main alternative to the dominant Democratic Party.
The Know Nothings supplemented their xenophobic views with populist appeals. At the state level, the party was, in some cases, progressive in its stances on "issues of labor rights and the need for more government spending" and furnished "support for an expansion of the rights of women, the regulation of industry, and support of measures which were designed to improve the status of working people." It was a forerunner of the temperance movement in the United States.
The Know Nothing movement briefly emerged as a major political party in the form of the American Party. The collapse of the Whig Party after the passage of the Kansas–Nebraska Act left an opening for the emergence of a new major political party in opposition to the Democratic Party. The Know Nothing movement managed to elect congressman Nathaniel P. Banks of Massachusetts and several other individuals into office in the 1854 elections, and it subsequently coalesced into a new political party which was known as the American Party.
