Which of the following was a significant contribution of George Washington during the Revolutionary War?

George Washington's command of the Continental Army was a pivotal contribution during the Revolutionary War. As the leader of this military force, he not only united the various colonial militias but also developed strategies that proved vital for achieving victory against British forces. Washington's leadership was characterized by his ability to inspire soldiers, maintain morale despite challenges, and adapt to evolving battlefield conditions. His role in key victories, such as those at Trenton and Yorktown, helped secure the independence of the American colonies.

In contrast, writing the Declaration of Independence was the responsibility of Thomas Jefferson and others in the Continental Congress, while signing the Treaty of Paris was a later event involving diplomats, and formulating the Bill of Rights was part of the constitutional process that took place after the war had concluded, making Washington's command of the Continental Army the most significant and direct contribution in the context of the Revolutionary War.
