Q. Costa Rica gained independence from which country in 1821?
Answer: Spain
Notes: Costa Rica gained independence from Sapin on 15 September 1821. Costa Rica was part of the Captaincy General of Guatemala of the Viceroyalty of New Spain within the Spanish Empire. It was described as the poorest and most miserable Spanish colony in all America. Costa Rica, itself, never fought for independence from Spain. In the Mexican War of Independence of 1810-1821, Spanish faced defeat and declared the independence of all Central America including Costa Rica. Costa Rica celebrates its independence day on 15 September every year.
