The Brazilian Army (Portuguese: Exército Brasileiro) is the land arm of the Brazilian Armed Forces. The Brazilian Army has fought in several international conflicts, mostly in South America during the 19th century. In the 20th century, it fought on the Allied side at World War I and World War II. Aligned with Western Bloc, it also had active participation in the Cold War, in Latin America and Southern Portuguese Africa, as well as taking part in UN peacekeeping missions worldwide since the late 1950s.
Domestically, besides having faced several rebellions throughout these two centuries, with support of key local elites and the big international capital, it also ended the monarchy and imposed on the rest of society its political views and economic development projects during the periods (1889–94, 1930–50* and 1964–85) that it ruled the country.
