About George Tupou V
George Tupou V (Siaosi Tāufaʻāhau Manumataongo Tukuʻaho Tupou; 4 May 1948 – 18 March 2012) was King of Tonga from 2006 until his death in 2012. He was the eldest son of King Tāufaʻāhau Tupou IV. After ascending the throne, George Tupou announced that he would relinquish most of the monarch's powers and be guided by the Prime Minister on most matters. A snap election in 2010 was the first to be called under the new system. Following his death, he was succeeded by his younger brother, Tupou VI. Having reigned for 5 years and 189 days, he was the shortest-reigning Tongan monarch since the declaration of the constitutional monarchy in 1875. == Early life and education == Prince Siaosi was born on 4 May 1948, as the eldest child of Crown Prince Tupoutoʻa Tungī (later King Tāufaʻāhau Tupou IV) and his wife Crown Princess Halaevalu, during the reign of his grandmother Queen Sālote Tupou III. He attended King's School and King's College, both in Auckland. This was followed by periods at The Leys School in Cambridge, and another school in Switzerland. He also studied at Oxford University and the Royal Military Academy Sandhurst in England. In addition to Tongan, he was fluent in English, French and German. == Crown Prince == After Siaosi's father ascended the throne in 1965, he was appointed Crown Prince of Tonga on 4 May 1966. In that role, he was better known by one of the traditional nobility titles, Tupoutoʻa, which has been normally reserved for crown princes since his father was given the title in 1935.
