Discuss the role of Thomas Jefferson in initiating the Lewis and Clark Expedition and its implications for U.S. policy towards westward expansion.
Thomas Jefferson was instrumental in initiating the Lewis and Clark Expedition as part of his vision for expanding U.S. territory and influence. He believed that exploring the Louisiana Purchase would open new avenues for trade and settlement while asserting American presence in the West. Jefferson's support of the expedition reflected a broader policy of manifest destiny that would shape U.S. expansionist goals in subsequent decades.

The Lewis and Clark Expedition had complex long-term impacts on U.S. relations with Native American tribes. While it fostered initial communication and cooperation with some tribes, such as through Sacagawea's guidance, it also laid groundwork for future conflicts as westward expansion continued.
