UN Forces Launch Inchon Landing in Korea

The Korean War erupted in June 1950 when North Korean forces invaded South Korea, pushing UN-backed defenders back to the Pusan Perimeter in the southeast.

Bolivian National Revolution Overthrows Government

Bolivia in the mid-20th century grappled with extreme inequality, dominated by a small elite controlling tin mines and land while the Indigenous majority remained disenfranchised. Mounting unrest against the military-backed regime of President Hugo Ballivián culminated in armed uprisings led by the Revolutionary Nationalist Movement. On April 9, 1952, revolutionaries seized key sites in La Paz, forcing Ballivián's government to collapse after several days of fighting. The new regime under Víctor Paz Estenssoro quickly enacted sweeping changes, including universal suffrage, nationalization of the tin industry, and agrarian reform redistributing land to peasants. These measures transformed Bolivian society and politics almost overnight.
