In olden times thrones were very unstable affairs, and kingdoms were overthrown in a twinkling. Readers of ancient history will recall many such instances of the downfall of earthly grandeur.

Alexander the Great overthrew Darius in the plenitude of his power; the Emperor Aurelian destroyed Palmyra and led Zenobia, the queen, in triumph to Rome, where she ended her days in peaceful retirement.

Rome, when mistress of the world, overthrew hundreds of monarchies, and killed or sent into exile innumerable kings. In the days of her decline, the people deposed their own rulers at such a rate that the imperial purple was finally put up at auction by the soldiery.

In later days, monarchies became more secure; but kingdoms were nevertheless overturned, and several royal rulers sent into exile, when not more severely punished. But, with passing years, revolutions became more rare, until Napoleon began his wars of conquest, and deposed kings as if they were playthings.

Since Napoleon's downfall, revolutions have become still more rare; yet monarchies are so many, and republican ideas are growing so rapidly, that scores of deposed rulers are in exile, pining for the days that will never return.

Perhaps the most notable is the Count of Paris, who recently paid a visit to this country. The count, it is true, has never reigned, so he cannot be said to have been deposed; but he claims descent from the Bourbon kings of France, and seeks to revive the ancient rule.

He is a resident of England, and is in easy circumstances. He has a rival for the throne in Prince Napoleon Bonaparte, who lives in luxurious exile in Switzerland.
