What significant conflict from 1910 to 1920 resulted in the removal of Porfirio Díaz from power?

The significant conflict that led to the removal of Porfirio Díaz from power between 1910 and 1920 is the Mexican Revolution. This revolution was primarily driven by widespread dissatisfaction with Díaz's authoritarian regime, which was characterized by extensive inequality, repression, and favoritism towards foreign companies. As different factions emerged, including peasants, workers, and the middle class, they united against Díaz's government in an effort to address social injustices and promote more democratic governance.

The Mexican Revolution is notable not only for its immediate political implications, leading to Díaz's resignation in 1911, but also for laying the groundwork for significant social reforms in Mexico. It ultimately changed the landscape of the nation, as it gave rise to a series of leaders and ideas that would shape Mexico's future. The other conflicts listed, such as the Cuban Revolution, Russian Revolution, and Spanish Civil War, occurred in different contexts and regions, and although they also involved struggles for change, they did not directly impact the power dynamics in Mexico during this period.
