Question

What are two effects of the Lewis and Clark expedition?

Answer 1

The Lewis and Clark Mission, also known as the Corps of Discovery Expedition, ran from August 31, 1803, to September 25, 1806, and was the first US expedition to travel the newly acquired western portion of the country following the Louisiana Purchase. Captain Meriwether Lewis and his close friend Second Lieutenant William Clark led a small group of US Army and civilian volunteers known as the Corps of Discovery. Before reaching the Pacific Coast, the expedition travelled west and crossed the Continental Divide of the Americas.

Complete answer:
The Expedition's long-term consequences are impossible to exaggerate. The increase in the northern plains fur trade between 1806 and 1812 was the most evident immediate result. Manuel Lisa and John Colter, both members of the Corps of Discovery, developed a short-lived trade route from northern South Dakota to Montana during that time. Following the War of 1812, the commerce was revived with the arrival of the Mountain Man period (1820-1845), during which more posts were built in the area. The American Fur Company of St. Louis, which owned Ft. Union was perhaps the epitome of these interests.
Artists such as Charles St. Memin, Paul Kane, George Catlin, and Karl Bodmer swiftly followed in the footsteps of the Expedition, presenting the world with astonishing depictions of life on the Northern Plains. These contributed to the popularisation of the west and would help to encourage immigration in the decades to come.
The aftermath of the Lewis and Clark expedition was anything but pleasant for Native Americans. The most disastrous event was the breakout of smallpox among the Mandan in 1837, which nearly wiped out the once-powerful tribe. The surviving Mandan and Hidatsa, whom the Arikara joined in Like-A-Fish-Hook settlement, benefited greatly from this disaster. The Three Affiliated Tribes traded, farmed, and hunted throughout the area. Worst of all, during the last quarter of the nineteenth century, the reserve system was established, taking away the vast bulk of the original people' land.
Residents on reservations such as Ft. Berthold were forced to convert to Christianity, give up hunting in favour of farming, and send their children to white boarding schools. This dreadful pattern was repeated throughout the trans-Mississippi west, wreaking havoc on all tribes engaged.
Effects of Lewis and Clark expedition
-National pride has risen.
-Families were given additional possibilities to cultivate.
-Unknown plant and animal species have been discovered.

Note:
By the mid- to late-nineteenth century, the military had established a presence in North Dakota, eventually erecting a series of forts to safeguard settlers and railroad workers. These military stations included Ft. McKeen, Ft. Abraham Lincoln. Later historic events, such as Chief Joseph and Sitting Bull giving up their fight against white encroachment on their territory and forced culture change, took place at several of these forts.
