The term ‘diaspora’ denotes the movement of people from their ancestral homeland to live and work in other country.Its origin is traced in thousands years back.In the Bible there is reference of diaspora. In the history of human civilization, we find a number of events of it. In the history of mankind, Jews people were the first mover. Their ancestor Abraham was forced to leave Iraq and took shelter in Egypt. In Egypt he was a mover also. Then his offspring Jews were forced to leave Egypt and settled themselves in Palestine. In Palestine the Jews were the exoduses. Later many of them were forced to leave Palestine during Islamic era. These Jews people shifted themselves in Europe and then America. Recently scholars have distinguished between different kinds of exoduses based on its causes such as imperialism, trade or labour migrations or by the kind of social coherence. The Aryans also left their central Europe thousands of years ago and settled in Indian continent. Globalization has facilitated people to people connection. Diaspora,in one country helps to bridge gaps between nations, hence it strengthens globalization. So, globalization has great influence on diaspora.
