The Statute of Westminster, enacted in 1931, primarily granted legislative independence to the dominions of the British Empire, including Canada, Australia, New Zealand, South Africa, and Ireland. It allowed these countries to make their own laws without requiring approval from the British Parliament.
However, it did not grant independence to the United States, as the United States had already declared its independence from Britain in 1776 and formally achieved it with the Treaty of Paris in 1783. Therefore, the Statute of Westminster is significant for Canada and other British dominions in their journey toward full sovereignty, but it is not related to American independence.
