Hiá»Âp Hòa (, , lit. "harmonization", 1 November 1847 â 29 November 1883), born Nguyá» n Phúc Há»Âng DáºÂt, and later known as Nguyá» n Phúc ThÃÂng upon ascending the throne was the sixth Emperor of the Vietnamese Nguyá» n dynasty and reigned for 3 months and 10 days, 130 days in total. During his brief reign, he used the era name Hiá»Âp Hòa, and is commonly referred to by this name. He was not granted a temple name and was posthumously conferred the title Prince of VÃÂn Lãng (æÂÂæÂÂé¡çÂÂ), with the Posthumous name Trang Cung (èÂÂæÂÂ).
Hiá»Âp HòaâÂÂs birth name was Há»Âng DáºÂt (æ´ªä½Â). He was the 29th and youngest son of Emperor Thiá»Âu Trá»Â, and his mother a Third-rank imperial concubine, Trðáng Thá» TháºÂn. In the 18th year of Emperor Tá»± ÃÂứcâÂÂs reign (1865), Há»Âng DáºÂt was granted the title Duke of Lãng (Lãng Quá»Âc công, æÂÂÃ¥ÂÂå ¬) by his elder brother, the emperor. In 1883, Emperor Tá»± ÃÂức died without a biological heir. According to his will, his adopted son Nguyá» n Phúc ïng Chân (later known as Emperor Dục ÃÂức) was to ascend the throne. However, after just three days of his reignâÂÂbefore he even declared a reign titleâÂÂthe new emperor was accused by two powerful regents of the court, Tôn Thất Thuyết and Nguyá» n VÃÂn Tðá»Âng and was deposed of and sentenced to death. The reasons are officially unclear. Historian, Pham Van Son wrote that Dục ÃÂức embarrassed the court with his debauchery at the coronation that Tôn Thất Thuyết revealed the incriminating sections of Tá»± ÃÂức's will. The court quickly ruled to execute him with poison for violating the mourning rules and buried him in an unmarked grave, a notably disproportionate sentence. Other contemporary historians make no mention of this episode and say that Dục ÃÂức was not executed but rather was left to die in captivity of starvation, a likelier sequence of events considering that he lived for another three months. With Dục ÃÂức in captivity, the regents named his 34-year-old uncle Hiá»Âp Hòa, as emperor. However, he presided over his nation's defeat by the French Navy at the Battle of ThuáºÂn An in August 1883, and on 25 August 1883 he signed the Treaty of Huế which made Vietnam a protectorate of France, ending Vietnam's independence. For this, he was deposed and forced by officials to commit suicide.
