Sepharad was the name the Jews gave to the Iberian Peninsula since the 2nd century AD. In modern Hebrew it means "Spain". When the Catholic Monarchs decided to expel the Jews who didn´t convert to Christianity in 1492, the Jews who left their kingdoms were called Sephardi or Sephardic. They settled down in different parts of the Mediterranean coasts: the most part of them settled down in the Ottoman Empire, especially in the cities of Salonica (present Greece) and Istanbul (present Turkey). Others settled down in Northern Morocco and Algeria. These Jewish communities preserved their language, a variation of old Castilian called Ladino or Judezmo. These Sephardi communities still speak this language. It´s very curious to listen to them, because you can have an idea of how old Castilian sounded in the 15th century like.

And here you have an example of Luz de Sefarad, a weekly radio programme totally spoken in Ladino. It´s broadcasted on Radio 5, a Spanish radio station, every Saturday at 19:40. If you click on Play, you will be able to understand almost everything:
