The idea of separation of powers as a political concept was developed by

The idea of separation of powers was developed by French philosopher Charles-Louis de Secondat, also known as Baron de Montesquieu. In his book "The Spirit of the Laws" published in 1748, he argued that the power of the government should be divided into separate branches to prevent any one person or group from becoming too powerful. Montesquieu suggested that these branches should be the legislative, executive, and judicial, with each branch having its own distinct powers and responsibilities. This idea has been influential in the development of modern democracies, including the United States Constitution, which is based on the principle of separation of powers.
