Had he stopped with this act of violence, his supporters might defend him on the doubtful ground of expediency; but he did not stop here. For centuries the tyranny of the sultans had been restrained by the derebeys, or lords of the valleys. They had been confirmed in the possession of their lands by Mohammed II, from which time they had continued to pay tribute to the sultan, and furnished him with quotas of troops. The sultan had no control over their lives or property. The subjects who tilled the productive lands of the valleys were suitably rewarded for their labor. The happiest and wealthiest peasants of the empire were found among the vassals of the beys, to whom they showed great devotion. These feudal lords, at a moment's warning, could summon twenty thousand men before their palace gates. They furnished the greater part of the sultan's cavalry force in war; and, unlike the pashas, had never raised the standard of rebellion; they had never wished for revolutions, and had never sanctioned insurrections. The possession of their property was guaranteed to them by inheritance, and they had no need of money with which to bribe the Sublime Porte. Mahmoud was bent on depriving them of their wealth and curtailing their privileges. They were rich, did not bribe him, and held hereditary possessions. These were unpardonable crimes in the sight of this exemplary reformer. The beys, who never dealt in treachery, were unsuspicious of others, and fell an easy prey. The peasants ceased to cultivate the lands from which they could no longer profit; and many of the wealthiest possessions became desolate. We must not think it strange, therefore, that the military power was prostrated, when, after having annihilated the Janissaries, Mahmoud deprived the derebeys of their ancient authority; for the military power of the empire rested chiefly in these two bodies. These innovations were made in the midst of a destructive Greek war, and at a time when the Danube and the Balkan were no longer formidable barriers to the Muscovite descendants of Ivan the Terrible, who brought back memories of the past, and threatened to avenge deeply treasured wrongs. Even at this critical period, when his army was annihilated, his fleet defeated, and the legions of Russia within a few days' march of Constantinople, Mahmoud threatened to feed his horses at the high altar of St. Peter's, and proclaim the religion of the prophet in the Muscovite capital. A threat that savored more of the seraglio than of the throne!
