sentences:  Although not as visible as the two other main factions in the Mexican Revolution because of their lack of a highly charismatic leader like Emiliano Zapata or Pancho Villa, there was a third group vying for power during the fighting in Mexico, and they played a critical role mainly because in the end, they won.This faction was known as the Constitutionalists, and consisted of predominately of liberal intellectuals and middle-class citizens – in other words, Mexicans who were not of purely indigenous backgrounds but also not of the elite class, and who therefore did not benefit all that much from the foreign investment boom of the Díaz reign.The Constitutionalists differed from the Zapatistas and Villa's men, who were fighting for a mostly singular cause.
