Badimo
Badimo ( Tswana badimo, literally "ancestors") is a name for the indigenous African Traditional Religion of Botswana. Although the CIA Factbook states that six percent of Botswanas are practitioners, in reality a great majority of Botswana follow at least some of the traditions deemed Badimo even if they are strong followers of another religion as well.
The term "Badimo", although usually translated as "ancestors" does not simply refer to people who are now dead, but rather to the "living dead". In the traditional African worldview, deceased ancestors continue to be present and are actively included in the daily life of individuals and tribes.
