Even as it recovered from the Great Depression, however, Argentina's increasingly urban and industrialized social profile bode poorly for the ruling Concordance, an alliance dominated by the conservative, rural landowner-oriented National Autonomist Party (who held power from 1874 to 1916).

Alvear was also deprived of a strong potential ally when the leader of the Democratic Progressive Party (PDP), Lisandro de la Torre, resigned from the Senate in protest over his inability to thwart the prevailing climate of corruption and impunity.
