Thiệu Trị
Hiệp Hòa was the 29th son of Emperor Thiệu Trị. After his nephew Dục Đức was deposed by court officials following a three-day reign in 1883 he reasserted the family's claim on the throne. However he presided over his nation's defeat by the French navy at the Battle of Thuận An in August 1883, and on 25 August 1883 he signed a treaty which made Vietnam a protectorate of France, ending Vietnam's independence. For this, he was deposed and forced by officials to commit suicide.
