Great Replacement

Great Replacement is a phrase used to describe a theory that immigration will cause the people living in a particular country to change, or be 'replaced', over time. The idea is that immigrants (people who move to a different country to live) will come to the country and take over. They will bring different cultures, customs, and beliefs, which may be different from the country's original population. This means that the country's original population will eventually be 'replaced' with the new immigrants and their cultures, customs, and beliefs.
