Diaspora means “to scatter” in Greek, but today we use the term to describe a community of people who live outside their shared country of origin or ancestry willingly or being forced but maintain active connections with it. A diaspora includes both emigrants and their descendants. Though the world has seen many diasporas, the study of diasporas has started to attract Scholars only in recent decades. There are some major reasons for which people move to a foreign country. In the primitive age, people travelled from one land to another in search of food shelter and security. There is a long historical background of diasporas all over the world such as the expulsion of the Jews from Judah, the movement of Aryans from Central Europe etc. But the Palestinian diaspora in the 20th century has attracted a lot of attention of the world leaders and peace loving people because of the unspeakable misery and plight of the Palestinian Muslims. Similarly, during the Liberation war of Bangladesh in 1971 many Hindus were compelled to disperse in India. From different studies and statistic, we can find a scenario of Bangladeshi diaspora all over the world. For example, the United Kingdom’s 2000 census found 300,000 Bangladeshis in the UK. The life of diaspora after migrating to another place is not always a happy one. Sometimes, they are deprived of enjoying fundamental rights and sometimes they can enjoy fundamental rights more than they could enjoy in their former place.
