They went their separate ways in 1806 & both became territorial governors: one of upper Louisiana, the other of Missouri

After their renowned journey through the American West, known as the Lewis and Clark Expedition from 1804 to 1806, Meriwether Lewis and William Clark parted ways. This expedition, commissioned by President Thomas Jefferson following the Louisiana Purchase, was a monumental exploration that significantly contributed to the understanding of the western territories of the United States. Subsequently, both Lewis and Clark took on roles as territorial governors.

Meriwether Lewis was appointed as the governor of the Upper Louisiana Territory in 1807 by Jefferson. His tenure as governor was crucial in managing the newly acquired vast territory, although it was also marked by personal and professional difficulties. These challenges included conflicts with local political and military figures, and struggles in governing the territory effectively. Lewis’ life came to a tragic and mysterious end in 1809, with circumstances that led some to speculate suicide as the cause.

William Clark, on the other hand, became the Governor of the Missouri Territory in 1813, a role he maintained until 1820. His governorship was instrumental in shaping the region, particularly in his dealings with Native American tribes. While he played a significant part in negotiating treaties, these often led to tribes ceding lands, reflecting the complexities of such interactions during that period. Clark remained a key figure in Native American relations beyond his governorship.

In present times, the achievements and journeys of Lewis and Clark are honored and remembered through various means. Their contributions to American expansion and exploration are celebrated through memorials, historical sites, and educational initiatives. One notable tribute is the Lewis and Clark National Historic Trail, which traces the path of their historic expedition and serves as a symbol of their exploration and governance legacy.
