George Tupou I (4 December 1797 – 18 February 1893), originally known as Tāufaʻāhau I, was the first king of modern Tonga. He adopted the name Siaosi (originally Jiaoji), the Tongan equivalent of George, after King George III of the United Kingdom, when he was baptized in 1831. His nickname was Lopa-ukamea (or Lopa-ʻaione), which translates to iron cable.
