Anatolia was a crossroads of agricultural communities, trading towns and empires long before a Turkish state existed. Hittite, Lydian and other political centres succeeded one another; Achaemenid, Hellenistic and later Roman rule connected the region to wider networks. Constantinople, founded as an imperial capital in 330, became the administrative and ecclesiastical centre of the Byzantine Empire. Greek, Armenian and other languages continued alongside one another.
From the eleventh century, Turkic-speaking rulers and communities gradually settled in Anatolia, following the Seljuk victory at Manzikert in 1071. The Ottoman dynasty grew from a regional principality into an empire governing territories in Europe, Asia and Africa. Provincial elites, trading towns and religious communities formed part of a changing system of rule; expansion and imperial commerce also involved warfare, taxation and forced displacement.
Defeat in the First World War, the empire’s dissolution and the war of independence led to the republic in 1923. The new state abolished the sultanate and caliphate and introduced sweeping reforms to the alphabet, education, law and administration. Population exchanges and nationalist politics changed demographics, while Kurds and other minorities faced assimilation policies and restrictions. Modern Turkey combines republican institutions with Ottoman legacies and marked regional differences.
