Zhu Youjian (朱由檢, 1611–1644), known by his era name Chongzhen ("lofty and auspicious") and the temple name Sizong, reigned from 1627 to 1644. He was the last emperor of the Ming dynasty to rule from Beijing.
Chongzhen was hard-working, frugal and deeply conscientious, but he was also suspicious, impatient and quick to blame his ministers. He inherited a state already close to collapse, with an empty treasury, a factional court, a Manchu threat in the northeast and famine in the northwest, and none of his efforts could reverse it. When rebel armies took Beijing in 1644, he took his own life.
