The treaty formalizing the new Greek monarchy, and the transfer of the Ionian Islands, is signed in London

The Greeks had overthown their Bavarian-born king a year earlier and after a debate among the European Powers and at the request of the Greek Parliament, Prince William of Denmark had agreed to become the new monarch.  As part of the agreement, the treaty formalizing the new Greek monarchy included the return of the Ionian Islands on Greece's western coast, including Corfu, then in British hands, to Greece.
