Answer:
Depending on the unique environment and history of each region, the consequences of European colonisation on ethnic groups and their property holdings might vary greatly. Indigenous peoples were frequently uprooted from their ancestral lands as a result of European colonisation, frequently by coercion, violence, or forced deportation.
Some of the arbitrary lines that European colonists created to separate indigenous regions and villages resulted in conflicts and tensions between various ethnic groups. This was especially true of Africa, where European powers partitioned the continent in 1884–1885 during the Berlin Conference, drawing arbitrary borders that divided various ethnic groups and led to ongoing tensions.
In other instances, settler colonies were established as a result of European colonisation, as European settlers appropriated indigenous peoples' former lands. This was the case, among other places, in North America, Australia, and New Zealand, when indigenous peoples were driven from their homes and had their property seized by European settlers.
Ultimately, it is evident that European colonisation had a considerable impact on ethnic groups' land holdings around the world and that many of the Europeans' borders continue to influence how different groups interact politically and socially today.
