- an area under full control of another and occupied by settlers from that country

Answer 1

The term that describes an area under full control of another country and occupied by settlers from that country is typically referred to as a "colony." In a broader context, it can also be termed as "settler colonialism," where colonizers establish a permanent presence and often displace the indigenous population.
