George Washington was considered to be the country's first federalist President. He was supportive of a sole government that centralized power and decided over the matters that concerned all of the states.
Within the first months of his presidency, Congress created executive departments like the Department of Treasury, State, War, and the Postmaster General. Washington proceeded to appoint Thomas Jefferson as Secretary of State, among other figures.
The Federal government proved to be not as strong as it should. This was proven with the Whiskey Rebellion in 1794. In order to raise money to pay the national debt, Congress imposed a tax on distilled spirits, which farmers considered to be unfair. Threats were placed against tax collectors.

The goal was to help these countries recover from World War II as well as develop a political and economic alliance.
