First Government Junta in Chile. Though supposed to rule only in the absence of the king, it is in fact the first step towards independence from Spain, and is commemorated as such.

Government Assembly of the Kingdom of Chile (September 18, 1810 – July 4, 1811), also known as the First Government Gathering, was the organization established to rule post-colonial Chile following the deposition and imprisonment of King Ferdinand VII of Spain by Napoleon Bonaparte. It was the earliest step in the Chilean struggle for independence, and the anniversary of its establishment is celebrated as the national day of Chile.
