Why did hostilities erupt in the philippines after the spanish american war

Emilio Aquino pre-empted the Democratic Process by declaring his Constittution and his Presidency without the will of the people. He also demanded troop entry into the City of Manila while the Spanish Army stationed in Manila was still in place. It had the possibility of becoming a bloodbath. It did anyway. Admiral Dewey did not have adequate ground forces to hold and protect the City, its civilian population, its Spanish prisoners and his own forces against the dozen or so warring Filipino factions intent on sacking and pillaging.

Fine until slavery ya ya haha
