M. Manouk bey was a prominent figure in the history of Romania and his efforts during the Russian-Turkish war of 1806-1812 proved to be vital. He received titles, political positions and awards from both Russian and Ottoman Empires. His influence on both empires played a crucial role as a mediator in Russian-Turkish negotiations, and it was in his private Bucharest house that the Russian-Turkish Peace Treaty was signed in 1812.

M. Manouk bey devoted his resources for charities in Romania and other countries. His endowments were used for building many schools and churches for different Armenian communities.

In the opening ceremony, speeches were delivered by the President of the Museum of Bucharest, M. Ionel Ionitan, Armenian Ambassador to Romania M. Yeghishe Sargsian, Member of Romania's Senate as well as President of Romania's Armenian Community M. Varoujan Voskanian.

The exhibition will last for one year and displays personal documents, notes, photos and other belongings of M. Manouk bey. For the occasion, a book about his life has also been published by the museum.
