Step-by-step explanation:
The Territorial Claims of North America after the War
After the war, the territorial claims of North America underwent significant changes. One of the most notable changes was the expansion of the United States' territorial claims, particularly in the West. Through various means such as treaties, purchases, and conflicts, the United States acquired vast territories including the Louisiana Purchase (1803), the annexation of Texas (1845), and the Mexican Cession (1848).
Additionally, other European powers such as Spain lost significant territory in North America. For instance, Spain lost Florida to the United States in 1819 through the Adams-Onís Treaty.
These changes in territorial claims helped shape the boundaries and composition of North America as we know it today.
