The Lewis and Clark Expedition, led by Meriwether Lewis and William Clark, explored the Pacific Northwest in 1804-1806. The expedition aimed to assess resources, declare sovereignty over Indian tribes, and find a direct water passage for trade. They encountered Native Americans, hired interpreters, and documented new animals. Thomas Jefferson ordered the expedition to claim the Pacific Northwest before the British. The expedition produced accurate maps, descriptions of plants and animals, and interactions with 70 Native American tribes. The expedition’s impact is still celebrated today, with buildings, structures, and animals named after Lewis and Clark.
The Lewis and Clark Expedition was one of the first large-scale explorations of the Pacific Northwest in the United States of America. This expedition was led by Meriwether Lewis and William Clark, two former soldiers chosen by then-President Thomas Jefferson. The cross-country expedition had several objectives, including judging the resources acquired in the Louisiana Purchase, declaring sovereignty over the Indian tribes of the area, and discovering a direct passage of water through the country to facilitate trade. Along the way, the group met many Native Americans, hired interpreters to communicate and trade with the Indians, and documented the appearance of animals they had never seen before.
Thomas Jefferson was keen to make the first discovery claim of the Pacific Northwest, before the British or anyone else. He ordered Meriwether Lewis, the chief officer of the Lewis and Clark Expedition, to follow the rivers, map the course and collect scientific data. While the expedition was the first official U.S. exploration of the Northwest Coast, Europeans and Canadians had been there before, the latter writing a book that influenced the president to begin his expedition.
The Lewis and Clark Expedition began with fewer than three dozen people in what is now known as Hartford, Illinois. It was the spring of 1804 when the party set out and followed the Missouri River to reach the first settlement en route. The expedition almost fought with the tribes on several occasions, especially when they needed to pass through inhabited territory or when animals or weapons went missing. Without the indigenous people of America, however, the Lewis and Clark Expedition would have failed due to starvation or having lost its way into the Rocky Mountains. For the most part, Lewis and Clark tried to keep trade negotiations peaceful and provide technology demonstrations and booze gifts when they could.
When the Lewis and Clark Expedition ended in 1806, the result was the very first accurate maps of the area and a better understanding of plants and animals previously unknown to the American people, though not indigenous. More than 140 maps, 200 plants and animals, and 70 Native American tribes were created, described, and annotated, respectively.
Because of the major contributions to scientific research and the impact the expedition had on the land gains of the United States, there are numerous buildings, structures, and animals named after Lewis and Clark. Also, their graves are still maintained and occasionally a place of celebration. During these celebrations, the plants discovered by the men are placed on their graves.
