And so time wore on, and Bosnia enjoyed a kind of fitful repose. There and in Herzegovina the feudal system had lost much of its primeval vigour, although a barbarous independence still prevailed, more especially in the latter province, where Ali Aga of Stolatz showed symptoms of forsaking the _treacherous fidelity_ which had secured for him his high position. Whatever feeling of disaffection might have been cherished, either in Bulgaria or Bosnia, was effectually checked: in the former by the judicious tyranny of Hussein, Vizier of Widdin, in the latter by the iron yoke of Tahir Pacha, who fully entered into the Sultan's projects for reform. The social condition of these two provinces rendered necessary a certain variety in the policy of their rulers. Thus, while Hussein may be regarded as the apostle of political Islamism in Europe, Tahir endeavoured to introduce the European element. He consequently identified himself, to a dangerous extent, with the Christian population, abolishing forced labour, equalising the taxes, and effecting other reforms calculated to upset the old, and establish the _Nisame Jedid_, or new order of things. At this juncture the flames of revolutionary war broke forth in Poland and Hungary. The proximity of these countries, and the affinity of their Slavonic origin, could not fail to disseminate the same spirit on the southern bank of the Save. A wild enthusiasm took possession of both Serbs[N] and Bulgares, before which the aged and decrepid Viziers felt themselves powerless. If it be difficult to realise the position of the Sultan, who thus found himself at variance with his Christian subjects in Bulgaria, and his Bosnian Spahis, the attitude assumed by these factions is equally incomprehensible. Blinded by one insane desire to throw off their allegiance to the Sultan, they espoused the Russo-Austrian cause, demanding their annexation to some Slave country. Thus, by a clever stroke of policy, Austria contrived to secure to herself the cooperation of both the Hungarian and Serb Slaves. And here we may note a curious coincidence, which still farther complicated matters. Whatever may have been their prejudices against the Slavonic Christians, the Bosnian Spahis found it expedient to demand the assistance, not only of the Servians, but of the Montenegrins, the most implacable of foes to the Turkish rule. These at first appeared likely to respond to the summons.
