The Joseon Army was the army of the Korean dynasty of Joseon (1392–1897). The army defended the northern borders but seldom defended the southern regions. The army was best known for fending off the Jurchen raids and conquering the Korean Peninsula. However, Joseon's neo-Confucianism disavowed military development, causing them to be vulnerable to Japanese and Manchu invasions. Despite this, Joseon kept strengthening the army until the 19th century, when western powers and the Japanese forced them to open doors and modernize the army.

The Command of the Northern Approaches was a military camp established during the late Joseon Dynasty in order to strengthen the defense of the outskirts of Hanseong through the Bukhansanseong Fortress. The Command of the Northern Approaches was established to strengthen the authority of the Seoin faction, which accompanied the king and princess and provided security after the Injo Coup. It also organized the local military and defense forces in Gyeonggi Province into a unified command structure.
