I read this article on Civil War or Ethnic Studies and found it interesting

https://journals.sagepub.com/doi/10.1177/0022343313512853#:~:text=Ethnic%20civil%20wars%20are%20common&text=Table%20I%20reveals%20that%20the,broken%20down%20along%20ethnic%20lines.&text=Even%20removing%20secessionist%20wars%20from,are%20considered%20ethnic%20civil%20wars.
