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. Its functions changed under different monarchs, and it went through multiple reorganizations, including the introduction of departments and the establishment of a General War Court. Despite these changes, its core responsibilities revolved around military administration, such as artillery, fortifications, commissariat, and payroll matters.
