Five Army Camps
The Five Army Camps (Korean: 오군영; Hanja: 五軍營; RR: Ogunyeong) was a central army and system established after the Imjin War for the defense of the capital city and its outskirts. Among them, the central military camps for defending the capital include the Military Training Agency (Hoonryeondo-gwan), Royal Guards Command (Eoyeongcheong), and Capital Garrison (Geumwiyeong). The defense of the outskirts of the capital was entrusted to the Command of the Northern Approaches (Chongryungcheong) and Royal Defense Command (Suyeochong). Among these, the Military Training Agency was established in 1593 (the 26th year of King Seonjo's reign) during the Imjin War, making it the earliest camp to be established. The Royal Guards Command was established in 1623 (the 1st year of King Injo's reign), followed by the Command of the Northern Approaches (Chongryungcheong) in 1624 (the 2nd year of King Injo's reign), and the Royal Defense Command (Suyeochong) in 1626 (the 4th year of King Injo's reign).
