The year 1932 was not only the year in which the famous carnival of Rio de Janeiro was organized for the first time, or the giant statue of the Christ the Redeemer was placed on top of the Corcovado mountain ridge: it was also the year of the last civilian war fought in Brazil.
On 9 July 1932, about 35,000 men from the federal states of Sao Paulo and Mato Grosso do Sul rose in arms against the dictatorship of Getúlio Vargas, demanding the return to constitutionality and democracy. This became known as the Constitutionalist movement and its members became known as the Paulistas.
The Brazilian government reacted with brute force: it deployed over 100,000 troops supported by heavy artillery and combat aircraft. The result was the biggest war ever fought in Brazil: the first ever campaign to see strategic aerial bombardment conducted in all of the Americas; the first aircraft shot down in air combats, and the first to see night bombing operations.
