The Minister of War was the Danish minister responsible for the administration of the Royal Danish Army.

After the 1901 Danish Folketing election, the Council President Johan Henrik Deuntzer of the Venstre Reform Party became the leader of Denmark's first liberal government. The resulting cabinet, which replaced the Cabinet of Sehested consisting of members of the conservative party Højre, was formed on 24 July 1901 and was called the Cabinet of Deuntzer. The formation of the new cabinet is referred to in Danish as "systemskiftet", the shift of government.
