To what extent were those leaders simply responding to or reflecting larger forces essentially beyond their control?

The leadership provided by particular individuals in each of the cases we have considered was important for both the overthrow of the old regime and the creation of the new one. Yet it would surely be inaccurate to say that what leaders did was the same in each case or that their leadership was equally significant in each case. Considering at least two specific cases, write an essay addressing the impact of revolutionary leadership on the course and outcome of the revolutions we have considered. To what extent were particular people indispensable both to the success of the revolution and the particular direction in which the revolution went thereafter? To what extent were those leaders simply responding to or reflecting larger forces essentially beyond their control?
