Answer
A coup d'etat is the illegal overthrow of a government, and it is often used to describe a violent or sudden takeover. In 1930, a military coup d'etat in Argentina ended Yrigoyen's second term. The coup was led by General José Félix Uriburu, who was opposed to Yrigoyen's policies and wanted to restore the power of the military. The coup was successful, and Uriburu became president.
