Occupation of Argentina (Failed Revolutions)

Upon the Invaison of Argentina during the Second Great South American War, the victorious powers of Chile and Portugal decided to jointly-occupy the nation of Argentina after hearing most of it's leaders fleeing to Andea. The Occupation was supposed to be temporary but after a rebellion against the last outposts under the control of the remnants of the Argentine Government. The Chileans and Portuguese made the occupation permanent and after the Treaty of Buenos Aires, the Portuguese handed over all of the land they occupied in Argentina to Chile.

Eventually the Occupation would last for 4 years, from 1846 to 1850 until the Chilean Government declared the merging of Argentina and Chile to form the Republic of Patagonia in which itself lasted for 10 years before being broken apart during the Second Argentine Revolution and the Argentine Civil Wars.
