The History of Tonga National Day?

King George Tupou I (formerly known as Tāufaʻāhau) unified the islands of Tonga in the early 19th century. A visionary leader, he sought to modernize and protect his kingdom from colonial powers.

On November 4, 1875, he proclaimed a Constitution, which established executive, legislative, and judicial branches of government, and declared fundamental rights for Tongan citizens.

Although Tonga entered into a Treaty of Friendship with Britain in 1900, becoming a British protected state, it retained its sovereignty.

The treaty ended in 1970, when Tonga formally became an independent state again, under the reign of King Taufaʻahau Tupou IV.

Initially celebrated as "Constitution Day", it honored the 1875 event directly.

In the early 2000s, it was renamed "Tonga National Day" to encompass broader national identity and unity, not just the constitutional document.
