President of Mexico
The history of Mexico has not been a peaceful one. After the fall of dictator Porfirio Díaz in 1910 because of the Mexican Revolution, there was no stable government until 1929, when all the revolutionary leaders united in one political party: the National Revolutionary Party, which later changed its name to the Party of the Mexican Revolution, and is now the Institutional Revolutionary Party (). From then until 1988, the PRI ruled Mexico as a virtual one-party state.
