Also, the Piasts were perceived to have defended Poland against the Germans, while the Jagiellons' main rival had been the growing Duchy of Moscow, making them a less suitable basis for post-war Poland's Soviet-dominated situation. The People's Republic of Poland under the Polish Workers' Party thus supported the idea of Poland based on old Piast lands. The question of the Recovered Territories was one of the few issues that did not divide the Polish Communists and their opposition, and there was unanimity regarding the western border. Even the underground anti-Communist press called for the Piast borders, that would end Germanisation and "Drang nach Osten".
