Final answer:
The nation that attempted to achieve its independence by declaring war against what would become the United States was composed of thirteen British colonies during the American Revolutionary War. No nation successfully achieved independence through war against the U.S. itself, but Native American tribes fought to protect their land.
Step-by-step explanation:
The question pertains to which nation attempted to achieve its independence by going to war against the United States. While several historical conflicts might be mentioned, the most fitting example is the instance where European settlers in North America declared independence. This refers to the American Revolutionary War, which began in 1775 and concluded with the signing of the Treaty of Paris in 1783. In this conflict, thirteen of Britain's colonies in North America declared their independence, resulting in the formation of the United States.
Another significant event was the War of 1812, also known as America's “Second War of Independence,” where the United States fought against Great Britain. However, in this case, the United States was already an independent nation defending its sovereignty, not attempting to achieve independence.
It is important to note that no nation successfully achieved independence through a war against the United States itself. However, individuals within the U.S., particularly Native American tribes, engaged in multiple conflicts to oppose U.S. expansion and protect their territories, albeit without success in gaining independence.
