Diaspora is a group of people living outside their original homeland. These communities are often spread across different countries and regions. The word is used in history and social studies to describe long-term movement and settlement.

The Jewish diaspora began over 2,000 years ago, while the African diaspora grew during and after the transatlantic slave trade between the 1500s and 1800s. People in a diaspora often keep connections through language, religion, food, and traditions. Cultural festivals, music, and family ties can link communities across continents.

Diasporas are studied using historical records, migration data, and cultural practices. They show how people remain connected to their origins while living in new places.
