Paper was invented in China around 105 A.D., by the eunuch Ts'ai Lun. According to the official history of the Han dynasty (3rd century A.D.), Ts'ai Lun was given an aristocratic title after he presented Emperor Ho Ti with samples of paper. In 751 A.D., Chinese papermakers were captured by the Arabs at Samarkand, and by 794 A.D. several state-owned paper mills operated in Baghdad. The Arabs were manufacturing paper in Spain around 1150. It was not until 1590 that the first English paper mill was founded, at Dartford.
