Fort Laramie was a significant military outpost established in 1834 in present-day Wyoming. It served as a key supply and communication center for westward expansion, particularly during the Oregon Trail and California Gold Rush. The fort was originally built to protect travelers and trade routes, and it played a crucial role in U.S. military operations in the region. Over the years, Fort Laramie became a focal point for interactions between the U.S. government and various Native American tribes, including the Lakota and Cheyenne. The fort was officially designated a national historic site in 1938, preserving its rich history and cultural significance.
