The Standing Rock Protest was a movement that began in 2016, primarily led by the Sioux Tribe and supported by various environmental activists. The protest aimed to stop the construction of the Dakota Access Pipeline, which was planned to run near the Standing Rock Sioux Reservation in North Dakota. Activists argued that the pipeline posed a threat to the local water supply and sacred lands. The protest drew national and international attention, with thousands of people gathering at the site to support the cause. Demonstrators faced law enforcement and legal challenges, but the movement highlighted issues of indigenous rights, environmental protection, and the importance of clean water.
