As a proud Tswana woman, I look at and explore our endogenous culture and heritage that we practice as the Tswana ethnic group which can be found unfamiliar in other ethnic groups. The first endogenous practice would be our leadership structure, as Tswana people we are governed by a king who took the reign from inheritance or lineage and becomes responsible for making decisions for the betterment of the village or community but he does not make this decision alone he has to appoint a "Lekgotla" which is a royal council that assists and advice the king with any decision he takes regarding the betterment of the village or of that of the community. The king cannot make decisions alone without consulting these people and they come to a certain agreement afterward regarding that decision before the king can act on it. 

The second endogenous thing will be the tradition that revolves around the funeral of a loved one. When a close family member such as a mother or father dies certain practices are followed regarding the passing as a tradition, which is before the burial the person closest to the deceased has to sit on a mattress for the duration of the funeral and after the family, they cut off their hair and are required to wear black clothes as a sign of mourning and will be given a certain period where they will take them off in a ceremony context to honor the late

This may be unfamiliar to other ethnic groups, but it is endogenous to the Tswana people and has been practiced for years as it holds the heritage and culture of the Batswana people.
