The period between the foundation of the Han dynasty and Wang Mang's reign is known as the Western Han (西漢; 西汉; Xīhàn) or Former Han (前漢; 前汉; Qiánhàn) (206 BC – 9 AD). During this period the capital was at Chang'an (modern Xi'an). From the reign of Guangwu the capital was moved eastward to Luoyang.
