The whole interior of the Balkan Peninsula formed at this period part of the dominions of Samuel King of the Bulgarians, who reigned over Bulgaria, Servia, inland Macedonia, and other districts around them. It was a strong and compact kingdom, administered by an able man, who had won his way to the throne by sheer strength and ability, for the old royal house had ceased out of the land during Swiatoslaf’s invasion of Bulgaria ten years before. The main power of Samuel lay not in the land between Balkan and Danube, which gave his kingdom its name, but in the Slavonic districts further West and South. The centre of his realm was the fortress of Ochrida, which he had chosen as his capital—a strong town situated on a lake among the Macedonian hills. There Samuel mustered his armies, and from thence he started forth to attach either Thessalonica or Adrianople, as the opportunity might come to him. The duel between Basil and Samuel lasted no less than thirty-four years, till the Bulgarian king died a beaten man in 1014. This long and unremitting struggle taxed all the energies of the empire, for Samuel was not a foe to be despised; he was no mere barbarian, but had learnt the art of war from his Byzantine neighbours, and had specially studied fortification. It was the desperate defences of his numerous hill-castles that made Basil’s task such a long one. The details of the struggle are too long to follow out: suffice it to say that after some defeats in his earlier years, Basil accomplished the conquest of Bulgaria proper, as far as the Danube, in 1002, the year in which Widdin, the last of Samuel’s strongholds in the North surrendered to him. For twelve years more the enemy held out in the Central Balkans, in his Macedonian strongholds, about Ochrida and Uskup. But at last, Basil’s constant victories in the field, and his relentless slaughter of captives after the day was won, broke the force of the Bulgarian king. In 1014 the Emperor gained a crowning victory, after which he took 15,000 prisoners: he put out the eyes of all save one man in each hundred, and sent the poor wretches with their guides to seek King Samuel in his capital. The old Bulgarian was so overcome at the horrible sight that he was seized with a fit, and died on the spot, of rage and grief. His successors Gabriel and Ladislas could make no head against the stern and relentless emperor, and in 1018 the last fortress of the kingdom of Ochrida surrendered at discretion. Contrary to his habit, Basil treated the vanquished foe with mildness, indulged in no massacres, and contented himself with repairing the old Roman roads and fortresses of the Central Balkans, without attempting to exterminate the Slavonic tribes that had so often defied him. His conquests rounded off the empire on its northern frontier, and made it touch the Magyar kingdom of Hungary, for Servia no less than Bulgaria and Macedonia formed part of his conquests. The Byzantine border now ran from
