Warriorhood & Nomadic way of life
The Maasai People have a reputation of being fierce warriors. Warriorhood prepares the young males to be responsible people both for themselves and for their community. Known for their bravery and courage, typically the Maasai warriors are never seen without their sharply honed spears. They protect the homestead, maintain water sources for the community, and protect the livestock from wild animals and theft. It is true that when they surrounded a marauding lion, they crossed on it and speared it to death.
Their nomadic way of life led to no attachments to possessions, and togetherness banded by the age sets of those who underwent circumcision ritual together. When a young man reaches junior adulthood he has the freedom to have sex with the wives of other elders, his comrades, if he so wishes. Likewise, a Maasai woman belongs to the entire age-set and sexual jealousy does not exist.
