customs
Chad, over time, has developed a cast system classified into hunters, tanners, and blacksmiths. Also in the country there is a group of slave descendants that live up in the north of the country. One major difference in marriage is that Chad accepts polygyny which is the process of having more than one wife. Higher education is an extreme issue in the country due to it being so underdeveloped except for the small and underfunded University of Chad. Chad doesn't observe a common standard of etiquette due to civil wars that have happened in past years.
