Therefore, Azerbaijan is a good example about the best way to efficiently improve integration of different components of the society, and abhor all sorts of exclusions for ethnic, social or religious purposes. This has been the case throughout the History of Azerbaijan, despite some periods of political turmoil, social unease or foreign involvement. In this respect, it is worth mentioning the example of few cemeteries in Baku, where deceased people of different faiths lay side by side and rest in peace. Cemeteries are also a cornerstone and a reference for scholars and researchers seeking to learn about Azerbaijan History. The way cemeteries are conserved and protected in Azerbaijan is really fascinating.
