What territory in North Africa constituted France's most important colony?

Algeria was France's most important colony in North Africa. Colonized in 1830, it became a significant part of France's national identity and economy, with a large number of French settlers, known as colons or pieds-noirs, establishing themselves there. The colony played a crucial role in France's agricultural and mineral production, making it vital to the French economy until Algeria gained independence in 1962.
