He was born in Tuszów Narodowy a village in the present-day Subcarpathian Voivodeship of south-eastern Poland, which at the time was part of Austria-Hungary, one of Poland's three partitioners. Prior to World War I, he established and participated in several underground organizations that promoted the cause of Polish independence. He fought with distinction in the Polish Legions during World War I, and later in the newly created Polish Army during the Polish-Soviet War (1919 to 1921). In that war he played a prominent role in the decisive Battle of Warsaw, when Soviet forces, expecting an easy final victory, were surprised and routed by the Polish counterattack.
