How did cuban and philippine revolutions against spain in the 1890s
affect us foreign influence

The revolutions in Cuba and the Philippines in the 1890's were very important for the US. Both revolutions for freedom were successful, so the Spanish influence was removed. The two newly independent nations though were weak after the revolutions, so with the Spanish out of the way, the US saw an opportunity to easily increase its influence in these territories. The US was quick to act, and it started to infiltrate and sponsor people that were going to work for its cause, resulting in spreading out of their influence in two territories of great strategic importance.
