Events of 1815
January - March
April - June
- April 5-April 12 - Mount Tambora in the Dutch East Indies blows its top explosively during an eruption, killing upwards of 92,000 and propelling thousands of tons of aerosols (Sulfide gas compounds) into the upper atmosphere (stratosphere). The high level gases reflect sunlight and cause the widespread cooling (known as a volcanic winter) and heavy rains of 1816, causes snows in June and July in the northern hemisphere, widespread crop failures, and subsequently famine, which is why 1816 becomes known as the Year Without a Summer.
- April 23- The Second Serbian Uprising against Ottoman rule takes place in Takovo, Serbia. By the end of the year Serbia is acknowledged as a semi-independent state; the ideals of the First Serbian Uprising have thus been temporarily achieved.
- May 3 - Battle of Tolentino: Austria defeats the Kingdom of Naples, which quickly ends the Neapolitan War. Joachim Murat, the defeated King of Naples, is forced to flee to Corsica and is later executed.
- May 30 - The Arniston, an East Indiaman repatriating wounded troops to England from Ceylon, is wrecked near Waenhuiskrans, South Africa with the loss of 372 of the 378 people on board.

- June 16 - Battle of Ligny: Napoleon beats the Prussians.
- June 16 - Battle of Quatre Bras: Marshal Ney gets a marginal win against the British and Allies.

July - September
- July 8 - Louis XVIII returns to Paris, and is 'restored' as King of France (he had declared himself king on June 8, 1795, at the death of his nephew, 10-year-old Louis XVII, and had lived in Westphalia, Verona, Russia, and England).
