During 1924, agreements were signed with companies from Czechoslovakia, France, Yugoslavia, Latvia, Germany, Romania, Switzerland, and Sweden, so that the first really international fair took place in 1925.

The intensive developments of the 1920s were crowned by the huge General National Exhibition (Polish: Powszechna Wystawa Krajowa, PWK, PeWuKa) of 1929 that was visited by 4,5 mln people.

During World War II, the company ceased to exist, its infrastructure was confiscated, and turned into a factory of Focke-Wulf, which made the PIF a military target for the Allied air forces.

In 1990 the Poznań International Fair transformed into a limited liability company with the State Treasure as one of its shareholders Since then the PIF is continuing to expand and enlarge its exhibition space.

MTP organises expositions of Polish leaders at over 50 renowned trade shows and exhibitions abroad in such countries as: Germany, Russia, Ukraine, Georgia, Czech Republic, Croatia, Bulgaria, Romania, Uzbekistan, Kazakhstan and Azerbaijan.
