Tonga's flag was adopted on 4 November 1875 under the constitution proclaimed by King George Tupou I. The Tongan Constitution explicitly states that the flag can never be changed, making it one of the most legally entrenched national symbols in the world.
The design features a red field with a white rectangle in the upper hoist canton, and within the canton a red couped (Greek) cross. The red colour represents the blood of Christ shed on the cross, and the white stands for purity — both a clear expression of the Christian foundation that King George Tupou I wrote into the constitution. Tonga is the only Pacific Island nation that was never formally colonised, though it was a British-protected state from 1900 until 1970.
