Activists from around the world gathered for the first-ever Indigenous Peoples March in Washington, D.C., on Friday. Issues including voter suppression, environmental protections and violence toward women and girls were at the forefront of the event.

“Our people are under constant threat, from pipelines, from police, from a system that wants to forget the valuable perspectives we bring to the table. But those challenges make us stronger,” said Chase Iron Eyes, an attorney at the Lakota People’s Law Project and member of the Standing Rock Sioux tribe.

Iron Eyes, who was a leader in the movement against the Dakota Access pipeline in 2016 and 2017, said he supports the “Green New Deal”—Rep. Alexandria Ocasio-Cortez’s proposal to address climate change through an economic stimulus program.

In the U.S., indigenous Americans are subject to disproportionate levels of police brutality, another focus of the march. “We must remind the world, again, that indigenous people matter. We are all made better when we respect one another and lift each other up,” Iron Eyes said.

This month, Canadian police arrested 14 people at a checkpoint where members of the Wet’suwet’en First Nation were trying to block construction of TransCanada’s Coastal GasLink pipeline. In Minnesota, indigenous people are fighting the construction of Enbridge’s Line 3 pipeline.

“We don’t want these tar sands going through our waters,” said Tara Houska, National Campaigns Director of the group Honor the Earth and adviser to Bernie Sanders’ 2016 presidential campaign.

“As one of the first Native American women in Congress, I see it as my responsibility to educate my colleagues about the federal government’s trust responsibility and provide a voice to advocate for those who have historically not had a seat at the table to make a long-awaited change,” she said in a statement before the rally.

Another key focus of the event was violence against women. More than 5,000 native women are estimated to be missing in the U.S. More than half of indigenous women in the U.S. have experienced sexual violence; the attacker is almost always a non-tribal member.
