The unification of South America took place throughout August of 2020, shortly after the Brazilian Union joined the Axis Coalition. The purpose of the uniication was to absorb the northern part of South America into the Brazilian Union to gain straight access to the south shores of the United States. This resulted in the declaration of war on the Brazilian Union by the Franco-German alliance and the addition of France and Germany to the Alliance. Germany, the third largest military in the world, made a very important improvement to the Alliance.
