The Kingdom of Greece was established in 1832 and was the successor state to the First Hellenic Republic. It was internationally recognised by the Treaty of Constantinople, where Greece also secured its full independence from the Ottoman Empire after nearly four centuries.

The First Hellenic Republic was the provisional Greek state during the Greek Revolution against the Ottoman Empire. From 1822 until 1827, it was known as the Provisional Administration of Greece, and between 1827 and 1832, it was known as the Hellenic State.
