London Protocol
Most of the Dodecanese Islands were slated to become part of the new Greek state in the London Protocol of 1828, but when Greek independence was recognised in the London Protocol of 1830, the islands were left outside the new Kingdom of Greece. They were occupied by Italy in 1912 and held until World War II, when they became a British military protectorate. The islands were formally united with Greece by the 1947 Treaty of Peace with Italy, despite objections from Turkey, which also desired them.
