The state of Ottoman administration in the Balkans continued to deteriorate throughout the 19th century, with the central government occasionally losing control over whole provinces. Reforms imposed by European powers did little to improve the conditions of the Christian population, while at the same time managing to dissatisfy a sizable portion of the Muslim population. Bosnia suffered at least two waves of rebellion by the local Muslim population, the most recent in 1850.[7] Austria consolidated after the turmoil of the first half of the century and sought to reinvigorate its longstanding policy of expansion at the expense of the Ottoman Empire.
