The rise and the survival of the Ottoman Empire for six centuries is one of the most important event of the European and Middle Eastern histories. At the apex of the Ottoman conquests in the mid-1500s, Süleyman the Magnificent pushed deep into Hungary and Mesopotamia, as well as making the empire the master of the eastern Mediterranean Sea. Later sultans advanced into southern Russia, Caucasia, Persia and north Africa. In concert with these military successes, the empire transformed itself into a sophisticated administrative entity of great strength, which encouraged diversity, culture, learning and religious activity. The Ottoman high tide reached the gates of Vienna in 1683, only to fail because of faulty command decisions and internal deficiencies. While the Ottomans were trying to counter the military reverses, the forces of the socio-economic revolutions in the West and rapidly evolving market economies added new stresses to it. A new generation of sultans and members of the governing elite evolved, who were convinced of the need for modernisation and westernisation (both terms have been used synonymously and interchangeably) and were committed to change in order to keep the empire intact. They did achieve some results but they failed to stop the interventions and machinations of the Great Powers, which sought to benefit from the empire’s collapse. The Ottoman Empire gained notoriety as the ‘Sick Man of Europe’ and additionally became a target for the forces of ethnic nationalism that fought to dismember it. The First World War became the swan song of the empire. For the first time since the 1680s, the Ottoman Army consistently defeated its European enemies. But it was too late. The empire, bankrupt and blockaded, could not match the resources of its enemies and surrendered.
