Answer: The United States is seeking to expand its borders into Spanish territories.
Step-by-step explanation:
The United States has endeavoured and succeeded in achieving its territorial expansion at the expense of Spain. The United States has had a problem with runaway slaves who have often resorted to Spanish-controlled territory, more precisely Florida. The government pointed to this problem, but the results only happened when General Andrew Jackson, with his troops, entered Florida territory and overthrew the Spanish governor.
Spain was at that moment preoccupied with the Latin American revolts. They agreed to leave Florida to America. In return, the US promised not to claim Texas and pay the debt owed to US citizens. The amount was five million dollars, all of which happened in 1819.
