Since the Medes belonged to the same Aryan family as the Persians, and had the same language, religion, and institutions, with slight differences, and lived among the mountains exposed to an uncongenial climate with extremes of heat and cold, and were doomed to hard and incessant labors for a subsistence, and were therefore--that is, the ordinary people--frugal, industrious, and temperate, it will be seen that what we have said of Persia equally applies to Media, except the possession by the latter of political power as wielded by the sovereign of a larger State. Before a central power was established in Media, the country had been--as in all nations in their formative state--ruled by chieftains, who acknowledged as their supreme lord the King of Assyria, who reigned in Nineveh. Among these chieftains was a remarkable man called Deioces, so upright and able that he was elected king. Deioces reigned fifty-three years wisely and well, bequeathing the kingdom he had founded to his son Phraortes, under whom Media became independent of Assyria. His son and successor Cyaxares, who died 593 B.C., was a successful warrior and conqueror, and was the founder of Median greatness. With the assistance of Nabopolassar, a Babylonian general who had also revolted against the Assyrian monarch, Cyaxares succeeded, after repeated failures, in taking Nineveh and destroying the great Assyrian Empire which had ruled the Eastern world for several centuries. The northern and eastern provinces were annexed to Media, while the Babylonian valley of the Euphrates in the south fell to the share of Nabopolassar, who established the Babylonian ascendency. This in its turn was greatly augmented by his son Nebuchadnezzar, one of the most famous conquerors of antiquity, whose empire became more extensive even than the Assyrian. He reigned in Babylon with unparalleled splendor, and made his capital the wonder and the admiration of the world, enriching and ornamenting it with palaces, temples, and hanging gardens, and strengthening its defences to such a marvellous degree that it was deemed impregnable.
