The Constitutional Convention is your answer.
I believe it's"Japan allowed less European trade after the Spanish conquered the Philippines, so traders hired private armies to force access to Japan".
It was the idea of wanting to have the individual states be more powerful than the federal government that guided the development of the articles of confederation, which is why they later proved to be inadequate and were replaced with the Constitution.
