The United States of America, commonly known as the United States, U.S.A. and the U.S., is a nation in eastern North America. It is composed of 42 states and one federal district. The nation borders Quebec, Acadia and Canada to the north and Mexico to the east.
The "American Policeman"
In the early 1800s, the United States was the sole independent state in the Americas (other than Brazil in 1822). The United States government, under president James Monroe, believed that it was the States' best intentions to stop or at least lessen European influence in the Americas, specifically South America, which had faced nationalist revolts. In 1823, the Monroe Doctrine was signed, and in the next few months, the United States declared war on the Kingdom of Spain, and helped spark the Spanish American Independence Wars. The war resulted in the independence of all Spanish states in South America. The peace treaty helped create four united republics, and the United States helped maintaining order and unity, avoiding rebellions such as the Colombian Crisis. The Doctrine also motive for aiding the French Canadians in the Lower Canada Rebellion. The United States did not generally explore imperialism outside of the Americas, having few expeditions to the Pacific and instead put more funding in ensuring peace in the Americas, becoming the "Policeman of the Americas".
The United States had gained land on several occasions.
In 1819, the United States had bought Florida from New Spain, after the dispute that had not been settled since American independence.
South American Wars of Independence
During the Spanish American Independence Wars, the United States had became involved in war against Spain to help the Spanish South American colonies gain independence. By the end of the war, the United States and the South American colonies gained full independence from Spain. In accordance with the Treaty of Paris, the United States had gained Cuba, while purchasing Puerto Rico and Dominico.
Lower Canada Rebellion
After the end of the Lower Canada Rebellion, of which the United States had successfully helped Lower Canada gain independence as Quebec, the Maine border dispute was officially settled, in favor of the United States. The Maine border was moved closer to the St. Lawrence River.
After the money-draining independence of New Spain as Mexico, the Mexican state was in need of immigrants to boost the economy. For about twenty years, American settlers had moved to large parts of Louisiana. By 1841, the American immigrants felt that the land had transformed into American land and deserved to be apart of the United States. The Louisiana War ended in favor of the US, and the whole of Louisiana was added to the United States.
Second World War
The Bahamas and the Turks and Caicos Islands were joined into the state of Bahamas, and the Cayman Islands were joined to the state of Cuba.
