One name, and one term. The name is "Ferdinand Marcos". The term is "martial law".
While Marcos was president, he declared martial law on the Philippines so that he can be president for a prolonged period of time. basically, almost nothing could happen in the Philippines without him noticing. But on one occasion, the Filipinos thought, enough is enough, and they decided to impeach Ferdinand Marcos. That's what the PP Revolution is all about.
