September 10th: A Day of Historical Milestones in Portugal and the World

September 10th marks crucial events in the history of Portugal and the world, from the demarcation of the Douro to Guinea-Bissau's independence and scientific advancements.

The date of September 10th is marked by significant events spanning centuries and various fields.

In 1756, the demarcated Douro region for Port wine production was created, a pioneering initiative by the Marquis of Pombal. Portugal also experienced the September Revolution in 1836, which re-established the 1822 Constitution, and in 1982, the new Penal Code was enacted.

Internationally, the date recalls the German occupation of Rome in 1943, Guinea-Bissau's independence in 1974 after a long liberation war, and the opening of Hungary's border with Austria in 1989, which accelerated the fall of communist regimes.

In science, the Large Hadron Collider was inaugurated in 2008, contributing to fundamental discoveries in physics, and in 2014, the Invictus Games began in London, promoting the recovery of injured military personnel through sport.
