What country gain its first independency?

The first country to gain independence in modern history is often considered to be the United States, which declared its independence from Great Britain on July 4, 1776. This event marked the beginning of a new nation and inspired other countries to seek independence. However, if considering the first successful independence movement in a broader historical context, Haiti's independence from France in 1804 is significant as it was the first successful slave revolt leading to the establishment of an independent nation.
