The Administrators

Presiding over a growing territorial and overseas empire takes a lot of power vested in the one-man office of the American presidency. The expansive scope of the President's authority had grown well beyond what a single man could control by the end of the 19th century; in the 20th century, presidents relied more and more on the growing power of the entirety of the executive branch. Administrations became exactly that -- sprawling networks of professionals and politicians that all reported to the top. Bureaucracy was the new order of the day, and it came often at the expense of domestic tranquility and international harmony. Theodore Roosevelt to Franklin D. Roosevelt, on the Administrators.
