Patricia Arquette took home the Academy Award for best supporting actress on Sunday night for her performance in Boyhood.

Arquette beat out Emma Stone, Keira Knightley, Laura Dern, and Meryl Streep to take home the Oscar.

At the podium, the Boyhood actress used her acceptance speech to make a powerful call for women's rights.

"To every woman who gave birth, to every taxpayer and citizen of this nation, we have fought for everybody else's equal rights," she said. "It's our time to have wage equality once and for all, and equal rights for women in the United States of America."

At last year's awards show, Lupita Nyong'o took home the honor for her work in 12 Years a Slave
