Malta has always been a maritime nation, and for centuries, there has been extensive interaction between Maltese sailors and fishermen and their counterparts around the Mediterranean and into the Atlantic Ocean. More significantly, by the mid-19th century the Maltese already had a long history of migration to various places, including Egypt, Tripolitania, Tunisia, Algeria, Cyprus, the Ionian Islands, Greece, Sicily and Lampedusa. Intermarriage with other nationals (especially Italians and Sicilians) was not uncommon. Migrants would periodically return to Malta, bringing with them new customs and traditions that over time have been absorbed into mainstream Maltese culture.
