What were the social changes that occurred in the Maasai pastoral community?

The social changes in the Maasai society occurred at two levels.
Firstly, the traditional difference based on age, between the elders and warriors, was  disturbed, though it did not break down entirely. Secondly, a new distinction between the wealthy and poor pastoralists developed. The pastoral communities in different parts of the world were affected in a variety of ways, by the changes in the modern world. New laws and new borders affected the patterns of their movement and their livelihood.
