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. During his reign, George Tupou V oversaw reforms within the Tongan honours system which both expanded the number of Orders in the Kingdom and created rules to make the award of these Orders more egalitarian.
