The US's History of Anti-Catholicism

Anti-Catholicism stretches back to the nation's colonial times, when some states barred Catholics from holding office, and continued through the mid-1800s, which saw the Know-Nothing party's campaign against Catholic politicians. Lynch mobs killed Italian immigrants and arsonists burned down Catholic churches.

Perhaps no publication captures the animus toward Catholicism at the start of the 20th century as vividly as the Menace, launched in an old opera house in Aurora in 1911, when the city's population was only a little over 4,000.

The Menace wasn't the country's first anti-Catholic newspaper, but it quickly became one of the biggest, eventually selling anti-Catholic books and launching a lecture series. Its editor, the Rev. Theodore C. Walker, claimed its target was not rank-and-file Catholics but the Catholic Church itself.
