Final answer:
Economic hardships, including high taxes, debts, and inflation from money printing, as well as social upheaval, like slaves fleeing to gain freedom, caused significant problems for patriots during the American Revolution.
Step-by-step explanation:
The changes that caused problems for patriots during the American Revolution primarily revolved around economic hardships and the repercussions of supporting the revolutionary cause. The economic crisis in 1786 and 1787, particularly in Massachusetts, led to farmers suffering due to high taxes and debts amidst a devaluing currency. Moreover, the necessary cost of supporting the military efforts through money printing caused rampant inflation, affecting soldiers and their families who faced shortages and could not keep up with the skyrocketing prices of goods such as beef and imported items like rum and sugar.
The Continental Congress struggled with financial obligations, leading to discontent and even food riots among the population. Additionally, social changes led to actions such as slaves seeking freedom from the chaos of war, which affected the composition of the patriot and loyalist forces.
