The beginning of the Ministry of Defence's operations is connected with the 1775 establishment of the Military Department within the
Permanent Council. In 1789, the Military Commission of the
Polish–Lithuanian Commonwealth was established, and from the
Constitution of 3 May 1791 was under the
Guardians of the Laws. Between 1793 and 1794, the department was restored in the Supreme National Council. When
Warsaw became part of the
Kingdom of Prussia after the
Third Partition of Poland in 1795, the Prussian Ministry of War headquarters was moved into the local
Copper-Roof Palace. Another War Ministry was established in the
Duchy of Warsaw. After the establishment of the
Stanisław Małachowski government on 5 October 1807, the War Directorate became the Minister of War. From 1807 to 1810, the number of ministry officials increased from a dozen to over one hundred. The ministry's activities ceased on 4 May 1813. In 1814, the Military Organizing Committee was established in
Paris to regulate the military affairs of the
Kingdom of Poland in 1815. After the
November Uprising and the introduction of the
Organic Statute of the Kingdom of Poland in the early 1830s, the distinctiveness of the Polish defence establishment from the Ministry of War of the
Russian Empire ceased to exist. On 30 January 1917, the
Provisional Council of State created an acting military commission, which was to deal with Polish military matters until a war office was organised. On 2 November 1918, the commission was transformed into the Ministry of Military Affairs, based at the
Copper-Roof Palace. During the London emigration of Polish power during World War II, on November 30, 1942, the name of the Ministry of Military Affairs was changed to the Ministry of National Defence. In 1944, under the
Polish Committee of National Liberation under the
communists controlled a National Defence Centre to manage the war front. After the war, the
Provisional Government of National Unity (TRJN) reestablished the Military Affairs Ministry, which would be replaced by the Ministry of National Defence in 1979 and was under the
Polish People's Army (LWP) in the
People's Republic of Poland. The ministry would be transferred from the LWP to the Polish Army in 1990. ==Organizational structure==
