On Saturday, activists marched to commemorate the 50th anniversary of the 1969 school walkouts in Abilene, Texas.
In total, about 300 students—mostly Mexican Americans—participated in the original march. Among the issues in which students expressed concern: The ability to speak Spanish at school without fear of suspension, and the equal opportunity to participate in sports.
The original protest lasted eight days, but the impact it had on Texas and the Chicano Civil Rights Movement still continues today.
Below are some of the iconic pictures from the walkout.
