June 25 and 26 will mark the 150th anniversary of the Battle of Little Big Horn, also known as Greasy Grass, where Indigenous forces defeated General George Custer and the 7th cavalry on the Montana plains, marking a historic moment in the fight against westward expansion.
Celebrations will honor the Oceti Sakowin (Lakota, Nakoda and Dakota people), Cheyenne and Arapaho people’s victory against the United States on June 25 and 26, 1876.
Roughly 19 tribes are involved in planning a week’s worth of festivities in Montana leading up to the anniversary. Tribal event organizers said they’re expecting roughly 1,000 horse riders, 500 motorcyclists and thousands of attendees.
The National Parks Service is also planning its own event at the Little Big Horn National Monument on June 25, 26, and 27. The National Park Service is expecting up to 10,000 attendees, according to its event webpage.
June 25, 26 and 27 the National Park Service is offering free admission to the Battle of Little Bighorn National Memorial.
Daily programming will begin at 9:30 a.m. local time each day. The commemoration will offer space for learning, reflection and cultural exchange and is organized in partnership with Tribal nations, descendants, historians, elected officials, authors, military representatives, and cultural organizations.
The visitor center will be closed during the event and the monument itself will be closed to the public prior to June 25.
Festivities will kick off June 25 with an opening prayer from Arvil Lookinghorse, a parade of nations (featuring a representative from each nation) and opening remarks from the Crow Chairman.
There will be space for cultural and educational booths at the site. However, no sales are permitted, according to a parks spokesperson who attended a planning meeting in Rapid City on June 4.
