It is known that the Anatolian Turks in first settled in Rumelia in 1262 with the escape of Izzeddin Keykavus II from Seljuks to Byzantium. Allotment of Dobruca Province to Keykavus and his soldiers by Emperor Michael VIII Palaiologos and passage of a pro-Keykavus Turkish group led by Sari Saltuk Baba from Anatolia to Rumelia became the start of a period in which Anatolian Turks had started to settle in the region. This process had been transformed into a systematic conquest and inhabiting policy in the Ottoman period. Especially in the 14th and 15th centuries, Turkish settlement had been considerably completed and continued throughout the 16th century. One of the most important indicators of this situation is the data collected from the tahrir notebooks. In this presentation, regarding the data of tahrir notebooks belonging to the Rumelian geography, it is aimed to follow the trace of the migration and the transformation it had caused in the Ottomans. Within this frame, the aim is to reveal what “Anadollu” (Anatolian) refers to as it is used both in place and person names, and, in a sense, to shed light on the migration in the Ottomans and the transformation it had caused.
