In 1844, when war between Spain and Morocco was threatened by reason of the frequent raids by the inhabitants of the Rif on the Spanish settlement of Ceuta, Spain declined arbitration on the ground that her rights were too clear for argument.
Isolated cases of piracy have occurred on the Rif coast of Morocco even in our time, but the pirate communities which lived by plunder and could live by no other resource, vanished with the French conquest of Algiers in 1830.
