Spanish Civil War Begins with Military Revolt
Spain's Second Republic, established in 1931 after King Alfonso XIII's exile, faced deep divisions between leftist reformers and conservative forces including the military, church, and aristocracy. Tensions escalated after the 1936 Popular Front election victory, prompting right-wing officers to plot a coup. On July 17, 1936, the uprising launched prematurely in Spanish Morocco when the conspiracy was discovered, with garrisons rising across the mainland the next day. General Francisco Franco soon assumed leadership of the Nationalists, who received support from Germany and Italy, while Republicans drew aid from the Soviet Union and international brigades. The conflict quickly divided the country into opposing zones marked by widespread violence.
Why it matters: The war served as a proxy conflict testing fascist and communist ideologies ahead of World War II, with foreign interventions shaping military tactics like aerial bombing. Its outcome installed Franco's dictatorship until 1975, isolated Spain internationally for decades, and influenced global perceptions of civil strife, authoritarianism, and the failure of non-intervention policies.
