Hugo Ballivián's government is overthrown by the Bolivian National Revolution, starting a period of agrarian reform, universal suffrage and the nationalization of tin mines

Hugo Ballivián Rojas (June 7, 1901 – July 15, 1993) was a prominent Bolivian military officer and political figure who briefly served as the de facto 44th President of Bolivia from 1951 to 1952. His tenure marked a tumultuous period in Bolivian history, acting as a final, desperate attempt by the established order to prevent sweeping social and political reforms that were already on the horizon. A seasoned career military man, Ballivián had ascended through the ranks, eventually becoming the Commander of the Bolivian Armed Forces. This position placed him at the heart of the nation's power structures, especially during a time when the military played a decisive role in political outcomes.

The circumstances of his rise to the presidency were highly unusual and extra-constitutional. In 1951, the sitting President, Mamerto Urriolagoitía, faced an impending political crisis. The general elections held that year had seen Víctor Paz Estenssoro, leader of the reform-minded Nationalist Revolutionary Movement (MNR), emerge victorious. Paz Estenssoro's platform promised profound changes, including land reform, nationalization of mines, and universal suffrage, which deeply threatened the traditional landowning and mining elite—often referred to as the "oligarchy." Fearing these reforms and determined to prevent Paz Estenssoro from taking office, Urriolagoitía executed what became known as a "self-coup" or "autogolpe." Instead of transferring power constitutionally, he resigned and, under the guise of maintaining order, called upon General Hugo Ballivián Rojas to assume executive power. This maneuver, widely dubbed the Mamertazo by the Bolivian public, effectively bypassed the democratic process and installed a military junta with Ballivián at its head. He took up residence in the Palacio Quemado, the historic presidential palace in La Paz, symbolizing the military's grip on power.

For the powerful, entrenched oligarchy, Ballivián represented their last hope to "turn back the hands of the clock" and preserve the old social and economic order that had prevailed since the late 19th century. However, the political and social ferment in Bolivia had reached a critical mass, and the situation proved to be beyond simple military control. Despite Ballivián's administration implementing stringent measures—including declaring a nationwide curfew, exiling numerous opposition leaders, and imprisoning others—the popular unrest persisted. Demonstrations, widespread work stoppages, and sporadic uprisings continued across the country, signaling the deep-seated desire for change among the populace.

The situation escalated dramatically when General Antonio Seleme, Ballivián's own Minister of Government, secretly aligned himself with the opposition. At this critical juncture, with Víctor Paz Estenssoro still in exile in Argentina, the leadership of the revolutionary plot fell to Hernán Siles Zuazo, a prominent figure within the MNR. Seleme's defection was a pivotal moment, providing crucial inside support to the plotters and setting the stage for a nationwide uprising. This collaboration catalyzed the events of April 9-11, 1952, which culminated in the transformative period known as the Bolivian National Revolution or the 1952 Revolution. This monumental event marked an irreversible watershed in Bolivian history, fundamentally altering the nation's political, economic, and social landscape.

During these tumultuous days, supporters of Ballivián, including significant contingents of the Bolivian armed forces, found themselves routed by a popular uprising. Crucially, defections from the military to the rebel camp swiftly tilted the balance of power. After several days of intense and violent armed confrontation, Ballivián's government crumbled. Recognizing the futility of further resistance, he sought and was granted asylum in the Chilean Embassy in La Paz, effectively ending his brief and controversial presidency. His departure signaled the definitive end of the political era that had characterized Bolivia from 1880 to 1952, paving the way for the profound changes ushered in by the National Revolution.

Hugo Ballivián Rojas remains a complex figure in Bolivian historical memory. To many, he is vilified as the last leader of the "Old Regime," a symbol of a conservative elite desperately clinging to power against the tide of popular demand for reform. Yet, others view him in more benign terms, as a military general who, in an exceptionally difficult and polarized period of Bolivian history, simply fulfilled the duty entrusted to him by a sitting president to maintain order. Regardless of the historical perspective, his presidency represents a critical turning point that directly led to one of Latin America's most significant social revolutions. After his tumultuous time in office, Ballivián retired from public life. He passed away on July 15, 1993, at the age of 92, long removed from the political maelstrom he once briefly led.
