On July 15, 1889 Dom Pedro II suffered an assassination attempt in Rio de Janeiro. Dom Pedro II, accompanied by his wife, daughter, and eldest grandson, went to the Sant’Anna Theater, now known as the Carlos Gomes Theater, in Rio de Janeiro. At the end of the performance, well past midnight, among the crowd, the Imperial Family made their way towards the exit. The imperial princess led the way, followed by the emperor, who had his arm linked with the empress, and behind them was Prince Pedro Augusto. Everything was going well until the emperors and princes reached the vestibule, where a sudden cry of “Long live the Republic!” erupted.
