汉光武帝
Although the year of his birth is uncertain, it is known that Du Shi was born in Henei, Henan province. Du Shi became an Officer of Merit in his local commandery before receiving an appointment in 23 as a government clerk under Gengshi Emperor (r. 23–25), following the revolt against the Xin Dynasty usurper Wang Mang (r. 9–23). However, Du soon after swore his allegiance to Emperor Guangwu of Han (r. 25–57), who is considered the true founder of the Eastern Han Dynasty (25–220).
