Hong Taiji (Manchu: ᡥᡠᠩᡨᠠᡳᠵᡳ; Chinese: 皇太极; pinyin: Huáng Tàijí; 5 November 1592 – 21 September 1643) was the second emperor of the Later Jin dynasty, which he renamed the Qing dynasty in 1636. He was a key figure in the transition from the Ming dynasty to the Qing dynasty in China and is considered one of the most significant rulers in Chinese history. Hong Taiji is known for his military and administrative reforms, which strengthened the Qing state and facilitated its eventual conquest of China. The name "Hong Taiji" is not directly translatable to Hebrew, but his title "Emperor" can be translated as "קיסר" (Kiser). In Mongolian, his name is transliterated as "Хон Тайж" (Khon Taij). Hong Taiji's reign was marked by significant military campaigns, including the conquest of the Ming dynasty's northern territories and the subjugation of the Mongols. He also implemented a series of administrative reforms, such as the establishment of the Eight Banners system, which integrated Manchu, Mongol, and Han Chinese forces into a unified military structure. These reforms laid the foundation for the Qing dynasty's subsequent expansion and rule over China.
