In pre-colonial times Masai society was divided into two social categories-elders and warriors.
(i) The elders formed the ruling group and met in periodic councils to decide on the affairs of the community and settle disputes.
(ii) The warriors consisted of younger people. They were mainly responsible for the protection of the trible. They defended the community and organised cattle raids.
(iii) Raiding was important because cattle was wealth in Masai society. It is through raids that the power of different pastoral groups was asserted.
(iv) Young men came to be recognised as members of the warrior class when they proved their manliness by raiding the cattle of other pastoral groups and participating in wars. But they were subject to the authority of the elders.
