The crisis of the fake letters was a political scandal in Brazil in 1921 involving two disclosed letters containing offenses against the Brazilian military and Nilo Peçanha. The letters were attributed to Artur Bernardes, then governor of Minas Gerais and a candidate for the 1922 presidential elections.[1][2]
The scandal that ensued intensified the military's opposition to Bernardes, who went on to win the election in March 1922, but faced the tenentist movement during his government, the beginning of a process of political rupture in the First Brazilian Republic that culminated in the Revolution of 1930.[3]
