Mayotte is divided into seventeen communes, in accordance with a decree of 1977-05-19. At that time, each commune was also a canton. On
1994-01-13, Mamoudzou canton was split into Mamoudzou I, Mamoudzou II, and Mamoudzou III cantons, but Mamoudzou commune was left untouched.
I treat the communes as secondary divisions.
