After World War II, Berlin was controlled by the Allied nations.

Explanation:

In 1945, shortly before the end of World War II, the allied countries met in the Yalta Conference, where they agreed to divide German territory into four occupation zones, each run by a country: USA, Great Britain, France and the Soviet Union.  

These four zones would be governed by a military representative appointed by the country in charge of the control of that area, although each would be politically and administratively independent.

In the division, Berlin was entirely under Soviet control but, being the capital, it was decided to remain under the control of an administration controlled by the four allied powers.
