Final answer:
The patriots won the Revolutionary War primarily due to the united front of colonists opposing Great Britain and the crucial military assistance from France.
Step-by-step explanation:
The top two reasons why the patriots won the Revolutionary War can be attributed to the ability to unite colonists from diverse backgrounds against a common enemy and the support from foreign allies, particularly France. The colonists' sense of community and shared purpose was exemplified by the signing of the Declaration of Independence and played a critical role in maintaining morale and fostering a spirit of resilience despite the hardships faced during the war. Additionally, the alliance with France provided the American colonists with necessary military support, which significantly helped in turning the tide of the war against the British forces.
