During the early 1800's, which was a major influence on the struggle for political independence in latin america?

1) European Enlightenment, 2) French revolution and Napoleon era (Ist French empire), 3) American Revolution

Explanation: at that time in Latin America it was quite difficult to find printing machine and authentically Latin American press. Books and journals were under the control of the church and there was a censorship which means that it was not so easy for new (revolutionary) ideas to reach this subcontinent. Nevertheless, revolutionary ideas reached Spain and Portugal so it helped very much for these ideas to reach big urban centers of Latin America.
