Philippine Revolution: After Spanish victory in the Battle of San Juan del Monte, eight provinces in the Philippines are declared under martial law by the Spanish Governor-General Ramón Blanco y Erenas.

Following a Spanish victory at San Juan del Monte, eight Philippine provinces were placed under martial law in 1896 to suppress the burgeoning revolution.
Governor-General Ramón Blanco y Erenas declared martial law over key provinces including Manila, Bulacan, and Cavite following the Battle of San Juan del Monte. Spanish troops had quelled a major rebel force, prompting fears of a widespread insurrection. The decree granted military courts the power to detain suspected revolutionaries and enforce curfews without civilian oversight. This harsh policy fueled Filipino anger and drove many neutral observers to join the revolutionary cause. Underground resistance networks strengthened in response, laying the groundwork for continued struggle for independence. The move highlighted the deepening rift between colonial authorities and the Filipino people at the dawn of the Philippine Revolution.

Fanni Kaplan shoots and seriously injures Bolshevik leader Vladimir Lenin, which along with the assassination of Bolshevik senior official Moisei Uritsky days earlier, prompts the decree for Red Terror.

In 1918, Fanni Kaplan attempted to assassinate Bolshevik leader Vladimir Lenin, prompting the onset of the Red Terror.
Fanni Kaplan, an anarchist-turned-opponent of the Bolsheviks, shot Lenin as he left a factory meeting in Moscow. Although Lenin survived, his injuries led to heightened paranoia among Bolshevik leaders. Shortly before, senior official Moisei Uritsky had been assassinated, further alarming the regime. Vladimir Lenin and the Communist Party responded by authorizing the Red Terror—a campaign of mass arrests and executions. The decree empowered the Cheka to eliminate perceived counter-revolutionaries without trial. This brutal campaign shaped the early Soviet state and set a precedent for political repression.

The Second Vienna Award reassigns the territory of Northern Transylvania from Romania to Hungary.

The Second Vienna Award in 1940 transferred Northern Transylvania from Romania to Hungary under Axis arbitration.
Mediated by Nazi Germany and Fascist Italy, the award redrew borders in Central Europe. Romania ceded over 43,000 square kilometers of territory with a large Hungarian minority. The decision fueled resentment and displacement among Romanian and Jewish communities. Tensions contributed to later ethnic conflicts and shaped wartime alliances. After World War II, the Paris Peace Treaties annulled the award and returned the region to Romania. The dispute over Transylvania remains a sensitive topic in Romanian-Hungarian relations.
