The Worcester Historical Museum is offering a free lecture on Saturday on a little-known part of New England history: Ku Klux Klan attacks on French Canadian immigrants who came to New England to take jobs in the local mills. Something you may not have know: ” At one point, New England KKK members outnumbered those in the south.”
The lecture is free with museum admission and starts at 10 am.
There’s an interesting (and slightly related) post on the Irish History Podcast that touches on Irish-American anti-racism in the early part of the 20th century:
