Final answer:
Key leaders of the American Revolution included John Adams, an advocate for independence; Thomas Jefferson, who drafted the Declaration of Independence; and George Washington, who led the Continental Army.
Step-by-step explanation:
The most prominent leaders during the American Revolution and their specific roles were: John Adams, who was a fervent advocate for independence and played a significant part in rallying support for the revolutionary cause; Thomas Jefferson, who famously drafted the Declaration of Independence, an act that enunciated the colonies' intent to form an independent nation; and George Washington, who was selected as the commander of the Continental Army and led the colonies through the Revolutionary War. These individuals, alongside others such as Benjamin Franklin and Patrick Henry, contributed significantly to the revolutionary efforts and the eventual establishment of the United States.
John Adams encouraged the drafting of state constitutions and was a key figure in the Continental Congress. Thomas Jefferson's role in penning the Declaration solidified his place in history as a key architect of American independence. George Washington's leadership on the battlefield provided the military support needed to sustain the Revolutionary cause. This collaborative leadership helped transition the American colonies from British rule towards independence and democracy.
