Pax Porfiriana – Latin for "The Porfirian Peace" – refers to the 33-year reign of dictator Porfirio Díaz, who ruled Mexico with an iron hand until toppled by the 1910 Revolution.
As a rich businessman (Hacendado) in the turbulent pre-revolutionary borderlands of the U.S. and Mexico, players compete to build business empires of ranches, mines, rails, troops, and banks while subverting opponents with bandidos, Indians, and lawsuits. Players win by toppling Díaz, either by coup, succession, revolution, or annexation of Mexico by the U.S. If Díaz remains firmly seated at the end of the game, then the player with the most gold wins.
