Following the German invasion of the Soviet Union in 1941, Konev took part in a series of major campaigns, including the battles of Moscow and Rzhev. Konev further commanded forces in major Soviet offensives at Kursk, in the Dnieper–Carpathian and Vistula–Oder offensives. In February 1944, he was made a Marshal of the Soviet Union. On the eve of German defeat, Konev's 1st Ukrainian Front was pitted against the armies of Georgy Zhukov in the Race to Berlin. Konev was the first Allied commander to enter Prague, the capital of Czechoslovakia, after the Prague uprising.
