Hundreds of the Knights Templar in France are arrested at dawn by King Philip the Fair, and later confess under torture to heresy.
King Philip IV of France orders the mass arrest of the Knights Templar on charges of heresy in 1307.
In the early hours of October 13, 1307, King Philip the Fair orchestrated the simultaneous arrest of hundreds of Knights Templar across France. Accused of blasphemy, idolatry, and secret rituals, the Templars faced brutal torture to extract confessions. Under duress, many knights admitted to heretical practices, providing Philip with a pretext to seize their vast wealth. The order’s Grand Master, Jacques de Molay, was later burned at the stake for relapsing into heresy. These events led to the dissolution of the Templars by Pope Clement V in 1312 and reshaped the balance of power between the monarchy and the Church.

France adopts the constitution of the Fourth Republic.
France adopted the constitution of the Fourth Republic on October 13, 1946, re-establishing republican governance after World War II.
On October 13, 1946, the French electorate approved a new constitution inaugurating the Fourth Republic. This constitution aimed to restore democratic institutions following the collapse of the Vichy regime. It created a parliamentary system with a clear separation of powers among the executive, legislative, and judicial branches. The President of the Republic held limited authority, while the National Assembly exercised significant legislative power. Despite its democratic intent, the Fourth Republic faced chronic political instability and frequent government changes. Its focus on economic reconstruction and European integration shaped post-war France. The constitution remained in force until 1958, when it was replaced amid the Algerian crisis. Nonetheless, the Fourth Republic laid foundations for modern French democracy and welfare state policies.
