Starting with President Jefferson's Louisiana Purchase in 1803 from Napoleon for $15 million, this era paved the way for the expansion of the United States from the Mississippi River to the Rocky Mountains. Significant events include the Adams-Onis Treaty, Texas Revolution, Mexican-American War, and the acquisition of Alaska. Discover how these pivotal moments shaped the nation, influenced settlement patterns, and led to the annexation of several states, culminating in the Gold Rush and Alaska's eventual statehood.
