====Calles presidency, 1924–1928====
{{Main|Plutarco Elías Calles}}
The [[1924 Mexican general election|1924 presidential election]] was not a demonstration of free and fair elections, but the incumbent Obregón could not stand for re-election, thereby acknowledging that revolutionary principle. He completed his presidential term still alive, the first since Porfirio Díaz. Candidate Plutarco Elías Calles embarked on one of the first populist presidential campaigns in the nation's history, calling for land reform and promising equal justice, more education, additional labor rights, and democratic governance.<ref>Jürgen Buchenau, ''Plutarco Elias Calles and the Mexican Revolution'' (2007) p. 103</ref> Calles tried to fulfill his promises during his populist phase (1924–26) and a repressive anti-clerical phase (1926–28). Calles, a vehement anticlerical, took on the church as an institution when he succeeded to the presidency, bringing about violent, bloody, and protracted conflict known as the [[Cristero War]].
