A military junta (ˈhʊntə,_ˈdʒʌntə) is a government led by a committee of military leaders. The term junta means "meeting" or "committee" and originated in the national and local junta organized by the Spanish resistance to Napoleon's invasion of Spain in 1808. The term is now used to refer to an authoritarian form of government characterized by oligarchic military dictatorship, as distinguished from other categories of authoritarian rule, specifically strongman (autocratic military dictatorships); machine (oligarchic party dictatorships); and bossism (autocratic party dictatorships).
A junta often comes to power as a result of a coup d'état. The junta may either formally take power as the nation's governing body, with the power to rule by decree, or may wield power by exercising binding (but informal) control over a nominally civilian government. These two forms of junta rule are sometimes called open rule and disguised rule. Disguised rule may take the form of either civilianization or indirect rule. Civilianization occurs when a junta publicly ends its obviously military features, but continues its dominance. For example, the junta may terminate martial law, forgo military uniforms in favor of civilian attire, "colonize" government with former military officers, and make use of political parties or mass organizations. "Indirect rule" involves the junta's exertion of concealed, behind-the-scenes control over a civilian puppet. Indirect rule by the military can include either broad control over the government or control over a narrower set of policy areas, such as military or national security matters.
Throughout the 20th Century, military juntas were frequently seen in Latin America, typically in the form of an "institutionalized, highly corporate/professional junta" headed by the commanding officers of the different military branches (army, navy, and air force), and sometimes joined by the head of the national police or other key bodies.
