Was the Mexican Revolution of 1910-1917 successful?
I would argue that it was not. The goals that the revolutionaries were supposedly pursuing really did not get accomplished, even though the PRI stayed in power for decades as the "revolutionary" party.
The revolution was supposed to bring about democracy and a system that would be more in tune with the needs of the common people. Instead, it brought about one party rule that was often authoritarian. Economically, it did not really do much to redistribute land the way it was supposed to (particularly outside of the presidency of Lazaro Cardenas). It did promote unions, but the unions often worked for the benefit of their leaders and the PRI rather than the benefit of the people.
In short, the revolution led to a system in which power remained pretty firmly held in the hands of a very few people. This was not what the revolution was meant to accomplish.
