Who among the following was also known for wanting to strengthen the nation and was a key figure in the early U.S. government?

John Dickinson was indeed a key figure in the early U.S. government and is best known for his efforts to strengthen the nation through the promotion of unity among the colonies and support for a stronger federal government. As a delegate to both the Continental Congress and a member of the Constitutional Convention, he worked on drafting important documents, including the Articles of Confederation. He advocated for a balanced approach to governance that recognized the need for a national government while also respecting state sovereignty. His writings, particularly "Letters from a Farmer in Pennsylvania," played a significant role in shaping public opinion toward the cause of independence and the importance of a unified government structure.

The other individuals mentioned were significant in their own right but are associated with a more anti-federalist perspective or a focus on state sovereignty rather than a strong national government. Patrick Henry, for example, famously opposed the Constitution in favor of stronger state rights, emphasizing a fear of centralized power. Samuel Adams was a strong advocate for independence and local governance, while Richard Henry Lee was known for his resolution calling for independence but also supported a more decentralized government.
