The Battle of Trenton was immensely important to the American Revolutionary cause because this was the war that showed the Americans could defeat the British and so it also helped in raising the morale of the revolutionaries. the Americans were very low on morale as they had been inflicted heavy defeats by the British army on several occasions before the Battle of Trenton. This battle gave the fledgling morale the boost to again rise up and fight the British army. It was a success that went a long way in getting the Americans their desired freedom from the British rule.
