Native American activists laughed, wept and sang their way out of Seattle’s City Hall on Monday after watching the City Council unanimously approve a resolution designating the second Monday in October as “Indigenous Peoples’ Day.”

“It’s beautiful to see,” said Matt Remle, a Seattle resident of Lakota heritage who wrote the first draft of the resolution, “the people walking out with smiles on their faces. Bringing that good energy and spirit to the people is what this was all about.”

The legislation provoked some opposition because October’s second Monday also is Columbus Day, a federal holiday named for explorer Christopher Columbus and widely marked by the celebration of Italian-American history and culture.
