The history of Romani in Greece goes back over 600 years to the 15th century. The name Gypsy sometimes used for the Romani people was first given to them by the Greeks who supposed them to be Egyptian in origin. Due to their nomadic nature, they are not concentrated in a specific geographical area but are dispersed all over the country. The majority of the Greek Romani are Orthodox Christians who speak the Vlachoura-Roma language in addition to Greek. Most of the Romani who live in Western Thrace are Muslims and speak a dialect of the same language.
