1933 Greek coup attempt

On the morning of March 6, 1933, following the parliamentary elections held on March 5, a military operation commenced in Athens, Greece under the leadership of the retired Lieutenant General Nikolaos Plastiras. Plastiras, who had withdrawn from political involvement since 1924, re-emerged to obstruct the People's Party from establishing a government, in support of the "National Coalition". This movement came in the wake of the electoral victory of the United Opposition, a coalition opposing Eleftherios Venizelos, spearheaded by Panagios Tsaldaris of the People's Party.

Evidence strongly suggests that Nikolaos Plastiras, the principal architect of the coup, proceeded with at least the tacit approval, if not the active encouragement, of Eleftherios Venizelos who was motivated by the poor results of the 1933 Greek legislative election.
