The Sarajevo Haggadah is a 14th century manuscript with a long and variegated history. It survived the Bosnian war in the 1990s. In 1992 it was rescued by a Muslim librarian named Enver Imamovic. He and some police officers recovered it from the museum, under gunfire and at great personal risk. You can read that story here. The Haggadah became well know, not least due to a 2007 historical novel by Geraldine Brooks, The People of the Book.
Much additional background is here and here and links.
The National Museum of Bosnia was closed for a while due to lack of funding. I'm glad to hear it's open again and that this precious manuscript is on display.
