"Frontier Figures" refers to individuals who played significant roles in the exploration and settlement of new territories, particularly in the context of the American West during the 19th century. These figures often include pioneers, explorers, and settlers who ventured into uncharted lands, facing challenges such as harsh environments and conflicts with Indigenous peoples. Notable examples of Frontier Figures include Daniel Boone, a famous frontiersman known for his exploration of Kentucky, and Lewis and Clark, who led an expedition to map the newly acquired western territories after the Louisiana Purchase. Their contributions helped shape the expansion and development of the United States.
