For centuries, people have had to migrate for individual or mass, voluntary or compulsory reasons. Those who leave their geography in order to settle in safer, more livable areas with a higher quality of life; they affect their new community as well as their own community. In this sense, migration emerges as a two-way concept. The new area settled especially in mass migrations; become open to change economically, sociologically and spatially. In the case of Turkey, it has received immigration for many years since its establishment, even before the Ottoman period, and has hosted mass groups. Turkey, which has migrated in masses sometimes due to economic reasons, sometimes agreements, sometimes wars and political crises, has managed the processes of entering and resettling into the country with different policies from time to time. International relations, with its domestic politics and immigration policies, experienced various ruptures and realized different practices for the resettlement of forced mass migrations. It has undergone various resettlement implementation processes, from settlement to location, from site assignment to free settlement. Throughout the thesis, Turkey's international forced mass migration experiences and examples of resettlement practices of these periods will be mentioned. One of the most important starting points of the study is to establish the relationship of all these processes with planning and to discuss the sustainability of instant and temporary solutions with planning in the longer term. This study aims to reveal how experienced migration experiences and applied resettlement policies have changed over time, and how predictability can be added when evaluated with planning.
