コロンブス・デー
Numerous efforts in North America have honored Native American people as part of Columbus Day, or by designating two holidays for the same date. Especially since Native American activism has increased since the 1960s and 1970s, a variety of protests have been staged against celebrating Columbus Day. These have included mock trials of Christopher Columbus in St. Paul, Minnesota, and protests and disruptions of Columbus Day parades in the United States.
