Final answer:
The statement is false; East Germany did adopt "Risen from the Ruins" as its anthem, while West Germany used a modified version of "Deutschlandlied" with only the third stanza.
Step-by-step explanation:
The statement that after WWII, the government of East Germany commissioned a new anthem, "Risen from the Ruins," while West Germany ceased to use an anthem altogether is false. After World War II, Germany was divided into East Germany (the German Democratic Republic or DDR) and West Germany (the Federal Republic of Germany or FRG). East Germany adopted "Auferstanden aus Ruinen" ("Risen from Ruins") as its national anthem, which was written in 1949. West Germany, on the other hand, retained the use of the national anthem "Deutschlandlied" but only the third stanza was adopted officially in 1952 due to the nationalistic overtones of the first stanza.
Despite the political division, the Iron Curtain could not suppress cultural uniqueness, as each side developed its own identities and symbols. The fall of the Berlin Wall in 1989 and the subsequent reunification of Germany in 1990 led to the merging of these two distinct regions under one government, adopting "Deutschlandlied" as the national anthem for the unified Germany.
