The War College (Swedish: Krigskollegium), originally established by Gustavus Adolphus in 1630, started as a military court but evolved into a central administrative agency responsible for the army.
Over time, it underwent several reforms, losing its central role and jurisdiction, and by 1866, it was absorbed into the Royal Swedish Army Materiel Administration.
Over time, this reorganized government agency became operational, with its first (provisional) regulations dated 20 March 1636, and its name changing to the War College.
At the same time, a separate Defence Commission was established alongside it, and in 1776, the Privy Councillor Carl Sparre was entrusted with the highest supervision of the military.
Both of these arrangements ceased in the 1780s; however, the War College was reorganized through a new instruction on 25 June 1782, with its most important feature being the division into five departments; only a few matters, such as legal cases and appointments, needed to be handled in plenary session.
With the beginning of 1866 (through an instruction dated 26 September 1865), the War College was transferred to the Royal Swedish Army Materiel Administration.
