The Home Army originated in the Service for Poland's Victory ("Służba Zwycięstwu Polski"), which General Michał Karaszewicz-Tokarzewski set up on 27 September 1939, just as the coordinated German and Soviet invasions of Poland neared completion. Seven weeks later, on 17 November 1939, on orders from General Władysław Sikorski, the Service for Poland's Victory was superseded by the Armed Resistance ("Związek Walki Zbrojnej"), which in turn, a little over two years later, on 14 February 1942, became the Home Army. During that time, many other resistance organisations remained active in Poland, though most of them, merged with the Armed Resistance or with its successor, the Home Army, and substantially augmented its numbers between 1939 and 1944.
