As Joel concludes in his latest excerpt from Mazower's history of Thessaloniki Salonica, terrorism doesn't work if you've got sufficiently determined polities as your enemies.
Most of IMRO's youthful members were not much bothered about the old disputes over dead sacred languages. What was the difference between the Greek of the liturgy and Old Church Slavonic? After all, hardly anyone understood either of them. Between these youthful secularists—whose motto was "Neither God nor Master"—and the devout supporters of the Bulgarian Exarchate a gulf emerged. Even within its own ranks, IMRO was deeply factionalized.... It might be going too far to say that IMRO was a more coherent and efficient force in the minds of its enemies than it was in reality but it certainly made little impact on the Ottoman state.
Politically IMRO was no more successful. Autonomy for Macedonia—which was the name Balkan Christians (and Europe) gave to the Ottoman vilayets of Salonica, Monastir and Uskub (Skopje)—was the goal: a "Bulgarian" governor would rule the province from Salonica, all officials would be "Bulgarian" Slavs, and Bulgarian would be an official language on an equal footing with Turkish. But faced with such a prospect, Greeks lent the support of their intelligence networks to the Ottoman authorities, and in Salonica itself Greek agents in the Hamidian police helped track IMRO sympathizers. Even more important an obstacle was the opposition of the Great Powers. Russia was now focused on central and east Asia—the conflict with Japan was only a few years away—and Britain and Austria saw the Balkans as one area where they could all work in harmony to support the status quo. They pushed—as Great Powers often will—for incremental reform rather than revolutionary change, and merely urged the Porte to take steps to improve the administration of the province.
Frustrated with the impasse which faced them, and believing that targeting the symbols of European capitalism might force the Powers to intervene, some young anarchists in Salonica took matters into their own hands, and decided to blow up the Ottoman Bank, in the European quarter. Under the influence of their beloved Russians, they called themselves the "Troublemakers," and later adopted the term "the Boatmen"—by which they identified themselves with those "who abandon the daily routine and the limits of legal order and sail towards freedom and the wild seas beyond them."...
The two surviving members of the plot, Shatev and Bogdanov, returned to Macedonia in the amnesty of 1908: Bogdanov died a few years later, but Pavel Shatev lived until 1952, becoming a lawyer in interwar Bulgaria and then minister of justice in the postwar Yugoslav republic of Macedonia.
IMRO sputtered on, although the bombers had dealt a near-fatal blow to the organization in the city. The better-known Ilinden uprising which took place on St. Elias's Day a few months later was the IMRO leadership's own anxious attempt to arouse a peasant revolt against Turkish rule. But its chief consequence was that several thousand more Christian peasants were killed by Ottoman troops in reprisal. The only success IMRO could claim after this series of bloody failures was a further diplomatic intervention by the Great Powers—their last significant involvement in the tangled Macedonia question before the Balkan Wars. The Ottoman authorities were forced to swallow the appointment of European officials to supervise the policing of the province. Among the younger army officers stationed there, resentment and a sense of humiliation led to the first stirrings of conspiracy against the Porte. On the other hand, Macedonia remained part of the empire and Hilmi Pasha continued as inspector-general. The one conclusion to be drawn from the rise and fall of IMRO was that ending Ottoman power in Europe would not come that way: the use of terrorism to embroil and involve the Great Powers was futile when the Powers upheld the status quo.
