Germany and Brazil have changed significantly throughout time in their internal organizations and in their external approach to other countries - Having shifted across history from open war to a strong alliance, Germany and the Prussian empire before it have had incredible importance in the building and development of Brazil.

The most significant presence of people of german origin can be seen in the south of Brazil, due to the waves of immigrants who arrived to Brazil in the XIX and early XX centuries from what was the Prussian empire and afterwards became the German empire - After this point in time, the history between the two nations was not the friendliest for a few decades, with aggressions eventually leading to war twice during the first half of the XX century.
