/u/wstd mentioned the Chinese name. In Korean, it's called the "woldo", and in Korean history it was definitely used during the Joseon dynasty (1392-1910) and it was possibly used during the Shilla dynasty, but I don't have any information on that time frame. However, it's proper use and instruction was laid out in military manuals as late as the 18th century.
