 During World War II, the manuscript was hidden from the Nazis by Dr. Jozo Petrovic, the director of the city museum and by Derviš Korkut, the chief librarian, who smuggled the Haggadah out to a Muslim cleric in a mountain village near Treskavica, where it was hidden in the mosque among Korans and other Islamic texts.During the Bosnian War of 1992–1995, when Sarajevo was under constant siege by Bosnian Serb forces, the manuscript survived in an underground bank vault.Afterwards, the manuscript was restored through a special campaign financed by the United Nations and the Bosnian Jewish community in 2001, and went on permanent display at the museum in December 2002.
