Articles relating to the Know Nothings, a nativist political movement in the United States in the 1850s, officially known as the Native American Party before 1855,  and afterwards simply the American Party. 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.
