The original arrangement was the articles of confederation, and explicitly weak federal government which was made as a loose federation of fairly powerful states, each allowed to mostly do their own thing, with a federal government that did as little as possible.
It didn't even make it ten years before it would have died.
The Constitution of the United States was written entirely to give the Federal government actual power and control and teeth. It was very clear that signing up to the United States meant individual states significantly giving away their power. That's why the constitution had so many extreme compromises, especially to slave states.
The US constitution entirely exists to codify the US being one nation.
