Brazil is a nation in Amazonia and is a Great Power.
Brazil remained a part of Portugal up until 1821, when they declared independence. Since then, they remained neutral until the First World War, when they send supplies to the allies. Then in the Second World War, they joined the allies and declared war on Britain (and the Axis) and invaded British Guyana (which also contained a good portion of OTL Venezuela as well), soon annexing the conquered territory. After the war, Brazil had a good increase on exports and also became a Great Power by 1995.
