Anti-Catholicism in the United States

The Ku Klux Klan, sometimes referred to as the Klan, is an American Protestant-led white supremacist and far-right hate group. Historians widely identify it as one of the earliest terrorist groups in the United States, citing its organized use of violence and intimidation to influence political and social conditions, particularly in the post-Civil War South. Across its three major iterations, the Klan has operated as a secret society made up of multiple affiliated organizations that used threats, assaults, and killings to advance their aims. Over its various eras, its targets included African Americans, Jews, Catholics, and immigrants.

The Puritans were English Protestants in the 16th and 17th centuries who sought to rid the Church of England of what they considered to be Roman Catholic practices, maintaining that the Church of England had not been fully reformed and should become more Protestant. Puritanism played a significant role in English and early American history, especially in the Protectorate in Great Britain, and the earlier European settlement of New England.
