The fourth Thursday in November marks Thanksgiving Day for most Americans. But to some, it’s the “National Day of Mourning.”

Since 1970, Indigenous people and their allies have gathered in Plymouth, Massachusetts on the fourth Thursday of November. This day, also home to the federal holiday of Thanksgiving, is known there by another name: National Day of Mourning.

For more than half a century, groups of Native Americans have been gathering on Thanksgiving to mark a National Day of Mourning at a historic site in Massachusetts. They honor their ancestors who were subject to atrocities by settlers in the 17th century.

The National Day of Mourning began in 1970 and is held annually in Plymouth, Massachusetts. • Indigenous participants mourn ancestors and protest systemic oppression. • Thanksgiving is seen by many Native people as a symbol of genocide and cultural erasure.

The ceremony dates back to 1970 when Kisha James‘ grandfather was invited to speak at a commemoration of the 350th anniversary of the Pilgrims’ arrival in Plymouth.

Since 1970, they have gathered in Plymouth to focus on the origins of Thanksgiving and to look at the issues that Native Americans face to this day.
