  1. after 431 BC; unfinished

    Thucydides, History of the Peloponnesian War

    Thucydides says the deepest cause of the great war between Athens and Sparta was the growth of Athenian power and the fear it caused in Sparta. Again and again he shows how power, fear and honor push states to act. He hoped his history would help later readers understand such times.

  2. c. AD 100–117

    Tacitus, The Annals and The Histories

    Tacitus writes the history of the early Roman emperors. He shows how one-man rule bred flattery, fear and spying, and how even histories were bent by those in power. He promises to write without anger or favor.

    “The histories of Tiberius, Caius, Claudius, and Nero, while they were in power, were falsified through terror, and after their death were written under the irritation of a recent hatred.”

    Tacitus, Annals, Book I, chapter 1. Translated by Alfred John Church and William Jackson Brodribb (Macmillan and Co., 1884). Internet Archive.

  3. written 1513; published 1532

    Niccolò Machiavelli, The Prince

    Machiavelli writes a guide for a new prince. He asks whether it is better to be loved or feared and answers that it is safer to be feared, if one cannot be both, though a prince must avoid being hated. Some readers see a cold handbook for tyrants, others a warning or a plain report of how politics works.

    “Upon this a question arises: whether it be better to be loved than feared or feared than loved?”

    Machiavelli, The Prince, Chapter XVII. Translated by W. K. Marriott (J. M. Dent, London, 1908). Project Gutenberg.

  4. 1599–1608

    William Shakespeare, Julius Caesar, Antony and Cleopatra, Coriolanus

    In Julius Caesar, Brutus joins the plot against Caesar out of fear that Caesar will become a king. Then Mark Antony turns the crowd with one speech. Shakespeare shows the power of words, and how quickly power slips from those who think they hold it.

    “Friends, Romans, countrymen, lend me your ears;”

    William Shakespeare, Julius Caesar, Act III, scene 2 (Mark Antony). (First printed in the First Folio, 1623). Project Gutenberg.

  5. 1651

    Thomas Hobbes, Leviathan

    Hobbes argues that without a power over everyone, life would be a war of each against all. People agree to give up their right to rule themselves to a sovereign who keeps the peace. He thought that power should be very great and undivided, since a divided power leads to civil war.

  6. 1748

    Montesquieu, The Spirit of Laws

    Montesquieu argues that anyone with power tends to abuse it. So liberty needs power to be divided: one body makes the laws, another carries them out and another judges. Each can then check the others.

    “To prevent this abuse, it is necessary from the very nature of things that power should be a check to power.”

    Montesquieu, Book XI, ch. 4. Translated by Thomas Nugent (The Spirit of Laws, revised edition, Colonial Press, New York, 1900). Internet Archive.

  7. 1787–1788

    Alexander Hamilton, James Madison and John Jay, The Federalist

    Writing to defend the new Constitution, James Madison accepts that people are not angels. So government must be given enough power to govern, and then be made to control itself. Separate branches, each with ways to resist the others, set ambition against ambition.

    “If men were angels, no government would be necessary.”

    Publius (Hamilton, Madison and Jay), Federalist No. 51 (Madison). (The Federalist Papers (Project Gutenberg text), 1788). Internet Archive.

  8. 1945

    George Orwell, Animal Farm

    Orwell's animal fable shows a revolution in which the new leaders become as bad as the old ones. The pigs use fear, lies and changed slogans to keep their power. Orwell meant it as a warning about how power can corrupt any cause.

For young readers

Power is being able to make things happen or make people do things. A team captain, a teacher and a president all have some power.

Power can help people, like a lifeguard keeping swimmers safe. But it can also be misused, like a bully on the playground. That's why many writers say power should have limits: the captain must follow the rules of the game too.

Talk about it

  • Is it better for a leader to be loved or feared? Why?
  • Why do you think the U.S. government has three branches?
  • Who has power over you? Who do you have power over, like a younger sibling or a pet?
  • Mark Antony changed a crowd's mind with a speech. Can words be a kind of power?
  • What stops a leader from becoming a bully?
