How Did the White Revolution Ultimately Undermine the Shah's Power?

How did the contradictions of the Shah's regime undermine his power rather than fortifying it as I imagine he had intended? As Kander, you mentioned, for example, that his land reform accelerated the mass proletarianization of peasants into peripheral urban slums. And why did ultimately the Islamic revolution break out when and how it did? The white revolution has the effect of really emphasizing these contradictions that come to be terminal for the government.
