The Serbian Assembly prepared the exhibition following the development of the Inter-Parliamentary Union (IPU) as the oldest international parliamentary organization in the world, with the help of the IPU Secretariat.

To emphasize the strong relationship of the IPU and the United Nations, the exhibition is also organized in the United Nations Office in Geneva and the United Nations Headquarters in New York.

IPU today has 179 members, national parliaments from around the world, and its biannual sessions are attended by over 1500 participants.

The Republic of Serbia and the National Assembly will host the coming 141st IPU Assembly in Belgrade, 13-17 October.
