Kosovo does not have an official religion. Like the rest of the country, the majority of Pristina's population consider themselves to be Muslim. However, religious practices may tend to be liberal. Many do fast for Ramadan and praying is widely practiced. The small minority of Pristina's religious population that is not Muslim practice Christianity in the form of Roman Catholicism and Eastern Orthodoxy. When Pristina was in the Serbian Empire in the Middle Ages, Eastern Orthodoxy was the predominant faith other than Roman Catholicism.
