The strikes and demonstrations remained isolated and had little practical effect, so Ferdinand remained in firm control. In 1908 the Young Turks, an energetic new generation of reformers, gained power in the Ottoman Empire. Their ascendancy temporarily restored the international self-confidence of the empire and threatened a renewed Turkish influence in the Balkans. To protect the territory it occupied in Bosnia and Hercegovina, Austria-Hungary annexed those regions. While the Turks were preoccupied with that situation, Ferdinand nationalized the Bulgarian section of his main international rail line and declared himself tsar of a fully independent Bulgaria. The Western powers, again seeing the threat of Ottoman collapse, were appeased by Russian-arranged financial compromises that saved face for the Turks. But tension between Bulgaria and Turkey increased dramatically after Ferdinand's declaration.

The arbitrary nature of Ferdinand's declaration also brought loud criticism from democratic-minded Bulgarian factions. Nonetheless, the grand national assembly held at Turnovo in 1911 to incorporate the terms of independence into the constitution, ratified Ferdinand's title and expanded his power in conducting foreign affairs.

By 1911 the BANU, led by Aleksandur Stamboliiski, had become the largest and most vocal opposition faction. Although the BANU never gained more than 15 percent of a national vote before World War I, the party had a large, unified following in the peasant class victimized by poor harvests, usurious interest rates, and high taxes. Stamboliiski's political philosophy put the peasant and rural life ahead of all other classes and lifestyles. Hating bureaucrats and urban institutions, he proposed a government that would provide representation by profession rather than party, to ensure a permanent peasant majority. His goal was to establish a peasant republic that would replace the conventional parliamentary apparatus established at Turnovo. The BANU was a controversial and powerful force in Bulgarian politics for the next two decades.
