Carbaneras is in the Mexican state of Tamaulipas. The name of the state is derived from Tamaholipa, a Huastec term in which the tam- prefix signifies "place where." As yet, there is no scholarly agreement on the meaning of holipa, but "high hills" is a common interpretation. (However, a native population of Tamaulipas, now extinct, was referred to as the "Olives" during the early colonial period, which is a likely Spanish transformation on holipa.)
The area currently known as Tamaulipas has been inhabited for at least 8000 years. Several different cultures (north coastal, south coastal, lowlands, and mountains) existed during that period.
Although Hernán Cortés conquered the Aztecs rather quickly, it took a gradual process for Spain to subjugate the inhabitants of Tamaulipas in the 16th and 17th centuries. The first permanent Spanish settlement in the area was Tampico in 1554. More work along these lines was done by Franciscan missionaries, although repeated indigenous rebellions kept the area unstable. What is now Tamaulipas was first incorporated as a separate province of New Spain in 1746 with the name Nuevo Santander. The local government capital during this time moved from Santander to San Carlos, and finally to Aguayo.
Carbaneras is bad Spanish for Las Cabaneras which means "The [Cattle] Herders" or in this case, cattle rustlers. This town is run by a corrupt mayor who turns a blind eye to the trade of rustlers, banditos and sea robbers that make this a thriving port. As long as everyone gets their cut he is happy, the locals are happy, and of course the pirates are happy to have such a safe haven.
