John Adams.
Step-by-step explanation:
John Adams was a Federalist who became the second president of the United States.
Before the United States Constitution, there was the Articles of Confederation. The Articles was very weak and gave little power to the central (national) government. Under the Articles of Confederation, the government could not tax the states, regulate trade, draft soldiers, or even create and enforce laws properly.
Soon, two groups formed that either opposed or supported the Articles of Confederation. Anti-Federalists supported the Articles of Confederation. They wanted a weak central government and powerful state governments, as they were scared that the central government would abuse its power onto the citizens. On the other hand, the Federalists opposed the Articles of Confederation. They wanted a strong central government and felt as if having a weak one was making the country weaker as a whole.
John Adams was a very famous Federalist. He wanted a strong national government and he supported the United States Constitution, which gave power to the national government. Adams was the vice president of George Washington, then became the second president of the United States.
