American revolutionaries claimed their independence from the British on July 4, 1776. As a result, they formed the United States of America.
During the year 1840, British colonists established several colonies. The United States had already established itself as a democratic nation.
In such circumstances, countries opted to join the United States rather than the United Kingdom.
Florida, Ohio, and Illinois became part of the United States of America. Texas joined the United States in 1836.
Several new states sided with the United States, and the country expanded.
The USA purchased Alaska from Russia in 1867, and Hawaii, the Philippines, Guam, and Puerto Rico were all taken over.
The United States did not take part in the World Wars directly. There were several soldiers killed, but the economy was unaffected.
It made money by supplying weapons to many governments.
During the same time, war devastated other countries, including as the United Kingdom, Germany, and France.
Because the USA did not incur losses, the Europeans continued to deposit their gold in the United States and to purchase US dollars, which were a stable currency.
To keep their currencies safe, 44 ally countries joined in 1944 and linked their currencies with US dollars.
As allied countries triumphed in WWII, the US dollar became the world’s reserve currency.
During 1950, there were two superpowers: the United States of America and the Soviet Union, who engaged in an ideological cold war.
The USA overthrew governments in nations where communist ideals were gaining hold. They supported terrorist organisations, executed revolutionaries.
Since the USA began interfering in domestic politics, several countries relied on it.
To counter the Soviet Union’s dominance, the US founded the NATO in alliance with European countries in 1949.
After the disintegration of the Soviet Union in the 1990s, the USA became the world’s superpower.
Other internal factors that contributed to the USA becoming a superpower were policies that recruited top personnel and encouraged innovation.
The USA, today has over 800 military bases.
