Today in History on September 20: Important Events, Current Affairs, GK and MCQs
September 20 gives competitive-examination students a particularly useful combination of maritime exploration, European unification, Indian railway security, cinema history, women's sports, environmental sustainability and university sport.
One of the earliest major events associated with the date occurred on September 20, 1519, when the expedition commanded by Portuguese navigator Ferdinand Magellan sailed from Sanlúcar de Barrameda in Spain. The expedition ultimately achieved the first circumnavigation of the Earth when the ship Victoria, commanded on the final stage by Juan Sebastián Elcano, returned to Spain in 1522.
On September 20, 1870, troops of the Kingdom of Italy entered Rome after opening a breach in the Aurelian Walls near Porta Pia. The event effectively ended the temporal rule of the Papal States over Rome and became one of the final major stages of Italian unification – the Risorgimento.
Cinema history remembers September 20, 1946 as the opening day of the first full Cannes International Film Festival after earlier plans for a festival had been disrupted by the Second World War. The first post-war festival brought together films and representatives from many countries.
Sports history associates September 20 with one of tennis's most famous events. On September 20, 1973, Billie Jean King defeated Bobby Riggs in straight sets – 6–4, 6–3, 6–3 – in the highly publicised “Battle of the Sexes” match at the Houston Astrodome.
For Indian students, September 20 is also observed as Railway Protection Force Raising Day. The RPF functions under the Ministry of Railways and evolved into an Armed Force of the Union following the 1985 amendment to the Railway Protection Force Act.
For 20.09.2026 current affairs, two international observances are especially valuable: World Cleanup Day 2026, focusing on food waste under the theme “From Clean Plates to Clean Cities”, and the 10th anniversary of International Day of University Sport.

Breach of Porta Pia
