Answer:
The cause of the Mexican Revolution was the 1910 election. This was a catalyst for the outbreak of political rebellion. The revolution was begun by elements of the Mexican elite hostile to Díaz, led by Madero and Pancho Villa. The Mexican people wanted their land back, Diaz made many improvements, but they were all detrimental to the poor.
US involvement with their revolution raises many questions because we were neglectful to aid the revolutionaries(the common and poor people) because Diaz was financially important to America's economy.
