The War of 1812 is often referred to as the second war for American independence . Why might it be called that?

The War of 1812 can be termed the "second war for American independence" because it solidified America's status as a sovereign nation, asserting its autonomy and demonstrating its ability to defend itself against foreign powers, particularly Britain. The conflict resolved lingering issues from the American Revolutionary War and safeguarded American interests, including maritime rights and territorial integrity.
