Greek War of Independence: A combined Egyptian and Ottoman army began an invasion of the Mani Peninsula, but were initially held off by the Maniots at the fortifications of Vergas.

The Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence fought by Greek revolutionaries against the Ottoman Empire from 1821 to 1829. In 1826, the Greeks were assisted by the British Empire, the Kingdom of France, and the Russian Empire, while the Ottomans were aided by their vassals, especially by the Eyalet of Egypt. The war led to the formation of modern Greece, which in subsequent years would be expanded to its current size. The revolution is commemorated by the Greek diaspora as independence day on 25 March.
