Sila 'o Tonga

The three swords represent the three dynasties or lines of the kings of Tonga, namely the Tuʻi Tonga, Tuʻi Haʻatakalaua and the current Tuʻi Kanokupolu). Tonga was united under King Siaosi Tupou I, who then orchestrated the formation of the first formal government and also the coat of arms. The dove with the olive branch symbolises the wish of God's peace to reign in Tonga forever (the dove and olive branch are taken from the story of Noah and the Great Flood in the Bible).

The three stars symbolise the main island groups of Tonga, which are Tongatapu, Vavaʻu and Haʻapai. The Crown symbolises the ruling monarchy, the King of Tonga. The text on the scroll at the bottom reads Ko e ʻOtua mo Tonga ko hoku Tofiʻa in the Tongan language: 'God and Tonga are my inheritance'.
