George Washington did not personally describe the purpose of checks and balances. However, the concept of checks and balances was a key part of the United States Constitution, which was written in 1787. The purpose of checks and balances is to prevent any one branch of government from becoming too powerful and potentially abusing its power. This system allows each branch of government to limit the powers of the other two branches, ensuring that no one branch has too much power. This helps to protect the rights and freedoms of the citizens and ensures that the government remains accountable to the people. The checks and balances system has been an essential part of the United States government for over two centuries and has helped to maintain a stable and democratic society.
