Who says power currupts abosultly power currupts abosultly?

The phrase "Power tends to corrupt, and absolute power corrupts absolutely" is attributed to British politician and historian Lord Acton. He expressed this idea in a letter to Bishop ManDELL Creighton in 1887, highlighting the dangers of unchecked authority. Acton's assertion emphasizes that those in positions of power are often susceptible to moral decay and misuse of their influence.
