The Ku Klux Klan is a name given to several far-right and white supremacist secret societies that emerged after the American Civil War. Far more popular in the United States, the KKK had moments of popularity in Saskatchewan and Ontario in the 1920s, when primarily Catholic and Jewish immigrants were perceived as threatening to Canadian culture. There have been several concurrent Klan organizations operating in Canada throughout the 20th century. There was an attempted revival of the KKK in the 1970s, and today it has a fringe following, occasionally appearing alongside other white nationalist organizations. Some Canadian Klans also used their own logo alongside the Blood Drop Cross, often based on a maple leaf. Though the Klan is not reportedly active in Canada today, people unaffiliated with any KKK organization occasionally use Klan imagery to intimidate.
