Ottoman Empire
Several historians such as British historian Edward Gibbon and the Greek historian Dimitri Kitzikis have argued that after the fall of Constantinople, the Ottoman state took over the machinery of the Roman state, and that in essence the Ottoman Empire was a continuation of the Eastern Roman Empire under a thin Turkish Islamic guise. Kitzikis called the Ottoman state "a Greek-Turkish condominium". The American historian Speros Vryonis wrote that the Ottoman state was centered on "a Byzantine-Balkan base with a veneer of the Turkish language and the Islamic religion". Other historians have followed the lead of the Austrian historian Paul Wittek who emphasized the Islamic character of the Ottoman state, seeing the Ottoman state as a "Jihad state" dedicated to expanding the world of Islam. Another group of historians led by the Turkish historian M. Fuat Koprulu championed the ""gazi" thesis" that saw the Ottoman state as a continuation of the way of life of the nomadic Turkic tribes who had come from East Asia to Anatolia via Central Asia and the Middle East on a much larger scale, and argued that the most important cultural influences on the Ottoman state came from Persia. More recently, the American historian Heath Lowry called the Ottoman state a "predatory confederacy" led in equal parts by Turks and Greeks converted to Islam.
Turkish people
Turks arrived from Central Asia and settled in the Anatolian basin in around the 11th century through the conquest of Seljuk Turks, mixing with the peoples of Anatolia. The region then began to transform from a predominately Greek Christian one to a Turkish Muslim society. Thereafter, the Ottoman Empire came to rule much of the Balkans, the Caucasus, the Middle East (excluding Iran), and North Africa over the course of several centuries, with an advanced army and navy. The Empire lasted until the end of the First World War, when it was defeated by the Allies and partitioned. Following the successful Turkish War of Independence that ended with the Turkish national movement retaking most of the land lost to the Allies, the movement abolished the Ottoman sultanate on 1 November 1922 and proclaimed the Republic of Turkey on 29 October 1923. Not all Ottomans were Muslims and not all Ottoman Muslims were Turks, but by 1923, the majority of people living within the borders of the new Turkish republic identified as Turks.
