When was Greece united for the first time?

Greece was united for the first time in 1827, following the Greek War of Independence against Ottoman rule. The establishment of the modern Greek state was formalized with the London Protocol in 1830, which recognized Greece as an independent sovereign nation. The initial territory included parts of the Peloponnese, central Greece, and some islands, marking a significant step towards unification. Subsequent expansions occurred as more regions joined the state in the following decades.
