Question: What was the name of the area in the highlands of central Anatolia ruled by Deiotarus? 
Context: Çayıralan is a town and district of Yozgat Province in the Central Anatolia region of Turkey.  The average altitude is 1,500 m above sea level.  According to 2000 census, population of the district is 32,880 of which 14,046 live in the town of Çayıralan.  It has one of the largest forest areas in Central Anatolia.  The district also possesses marble mines. Laodicea Combusta (Greek: Λαοδίκεια Κατακεκαυμένη , "Laodikeia Katakekaumenê", "Laodicea the Burned") or Laodicea (Greek: Λαοδίκεια ), and later known as Claudiolaodicea, was a Hellenistic city in central Anatolia, in the region of Pisidia; its site is currently occupied by Ladik, Konya Province, in Central Anatolia, Turkey. The Epistle to the Galatians, often shortened to Galatians, is the ninth book of the New Testament.  It is a letter from Paul the Apostle to a number of Early Christian communities in Galatia.  Scholars have suggested that this is either the Roman province of Galatia in southern Anatolia, or a large region defined by an ethnic group of Celtic people in central Anatolia. Koçgiri (also Qoçgiri or Koçkiri) is a Kurdish-Alevi tribe in Central Anatolia and Eastern Anatolia Region, Turkey.  They mainly speak Kurmanji language.  Koçgiri tribe in Turkey mostly live in İmranlı, Zara and Refahiye districts of Sivas province, as well as in several villages in Sarız, Göksu districts. Adobogiona (fl.  c. 90 BC - c. 50 BC) was a Galatian princess from Anatolia.  She was the daughter of a Celtic noble named Deiotarus and sister to Brogitarus from the Tolistobogii tribe.  Her cousin was the tetrarch Deiotarus Philoromaios, a Roman client king of Galatia, who had a daughter of the same name. Eretnids (Turkish plural; "Eretnaoğulları") was an Anatolian beylik that succeeded the Ilkhanid governors in Anatolia and that ruled in a large region extending between Caesarea (Kayseri), Sebastea (Sivas) and Amaseia (Amasya) in Central Anatolia between 1328–1381.  The dynasty was founded by Eretna, an officer of Uyghur origin in the service of Ilkhanid governors of Anatolia.  Although short-lived, the Beylik of Eretna left important works of architecture.  The name of Eretna may be derived from Sanskrit word "Ratna" "Jewel" or Tuvan (Turkic) language word "Ertine" (эртине) "treasure,jewel, value, esteem, appreciate, dignify, treasure, cherish ". Ancient Galatia ( ; Greek: Γαλατία , Turkish: "Galatlar" ) was an area in the highlands of central Anatolia (Ankara, Çorum, Yozgat Province) in modern Turkey.  Galatia was named for the immigrant Gauls from Thrace (cf. Tylis), who settled here and became its ruling caste in the 3rd century BC, following the Gallic invasion of the Balkans in 279 BC.  It has been called the "Gallia" of the East, Roman writers calling its inhabitants "Galli" ("Gauls" or "Celts"). Ottoman Greeks (Greek: Οθωμανοί Έλληνες, Turkish: "Osmanlı Rumları" ) were ethnic Greeks who lived in the Ottoman Empire (1453–1921), the Republic of Turkey's predecessor.  Ottoman Greeks, who were Greek Orthodox Christians, belonged to the Rum Millet ("Millet-i Rum").  They were concentrated in what is today modern Greece, eastern Thrace (especially in and around Constantinople), western Asia Minor (especially in and around Smyrna), central Anatolia (especially Cappadocia), northeastern Anatolia (especially in Erzurum vilayet, in and around Trebizond and in the Pontic Mountains, roughly corresponding to the medieval Greek kingdom of Pontus).  There were also sizeable Greek communities elsewhere in the Ottoman Balkans, Ottoman Armenia, and the Ottoman Caucasus, including in what, between 1878 and 1917, made up the Russian Caucasus province of Kars Oblast, in which Pontic Greeks, northeastern Anatolian Greeks, and Caucasus Greeks who had collaborated with the Russian Imperial Army in the Russo-Turkish War of 1828-1829 were settled in over 70 villages, as part of official Russian policy to re-populate with Orthodox Christians an area that was traditionally made up of Ottoman Muslims and Armenians. Deiotarus of Galatia (in Galatian and Greek Deiotaros, surnamed Philoromaios;  105 BC 42 BC, 41 BC or 40 BC) was a Chief Tetrarch of the Tolistobogii in western Galatia, Asia Minor, and a King of Galatia ("Gallo-Graecia").  He was considered one of the most adept of Celtic kings, ruling the three tribes of Celtic Galatia from his fortress in Blucium. The Kurds of Central Anatolia (Kurdish: "Kurdên Anatolyayê/Anatolê", Turkish: "Orta Anadolu Kürtleri" or "İç Anadolu Kürtleri" are the Kurdish people who have immigrated and been in Central Anatolia (present day Aksaray, Ankara, Çankırı, Çorum, Eskişehir, Karaman, Kayseri, Kırıkkale, Kırşehir, Konya, Nevşehir, Niğde, Sivas, Yozgat provinces) since about 16th century.
