Razgrad Province in the context of "Ludogorie"

Razgrad (Bulgarian: Разград [ˈrazɡrat]) is a city in Northeastern Bulgaria in the valley of the Beli Lom river that falls within the historical and geographical region of Ludogorie (Deliorman). It is an administrative centre of Razgrad Province.

Isperih (Bulgarian: Исперих [ispɛˈrix]; Turkish: Kemallar) is a town in northeastern Bulgaria, part of Razgrad Province, situated in the central part of the Ludogorie region. It is the administrative centre of the eponymous Isperih Municipality. As of December 2021, the town had a population of 7,424.

Isperih was called Kemallar during the Ottoman rule of Bulgaria and was later renamed in honour of Bulgarian khan Asparuh, whose name in Slavic was Isperih.

Samuil (Bulgarian: Самуил [sɐmuˈiɫ]; Turkish: Işıklar) is a village in northeastern Bulgaria, part of Razgrad Province, located in the geographic region of Ludogorie. It is the administrative centre of the homonymous Samuil Municipality, which lies in the southeastern part of the Province. As of December 2009, the village has a population of 1,543 inhabitants.

Samuil lies among the Samuil Heights in the Ludogorie Plateau, near the second highest hill in the Danubian Plain (501 metres). The population consists of Bulgarians, Turks and Romani. The area was inhabited by the Getae and the Romans in Antiquity and by the Slavs and Bulgars in the Middle Ages. It was part of the First Bulgarian Empire and the Second Bulgarian Empire, but fell under Ottoman rule as early as 1388. The construction of Baron Hirsch's Rousse-Kaspichan-Varna railway line in 1867-1868 turned the small village of Ishiklar into a railway station of local importance, with the first settlers being Greek merchants and harvesters. After the Liberation of Bulgaria, many Bulgarians settled in the village, which was renamed to Gara Samuil ("Samuil Station") and then to Samuil in honour of the medieval tsar Samuil of Bulgaria.

Bulgarian Turks (Bulgarian: български турци; Turkish: Bulgaristan Türkleri) are ethnic Turkish people from Bulgaria. According to the 2021 census, there were 508,375 Bulgarians of Turkish descent, roughly 8.4% of the population, making them the country's largest ethnic minority. Bulgarian Turks also comprise the largest single population of Turks in the Balkans. They primarily live in the southern province of Kardzhali and the northeastern provinces of Shumen, Silistra, Razgrad and Targovishte. There is also a diaspora outside Bulgaria in countries such as Turkey, Austria, the Netherlands, Sweden, Norway and Romania, the most significant of which are the Bulgarian Turks in Turkey.

Bulgarian Turks are the descendants of Turkish settlers who entered the region after the Ottoman conquest of the Balkans in the late 14th and early 15th centuries, as well as Bulgarian converts to Islam who became Turkified during the centuries of Ottoman rule. However, it has also been suggested that some Turks living today in Bulgaria may be direct ethnic descendants of earlier medieval Pecheneg, Oghuz, and Cuman Turkic tribes. According to local tradition, following a resettlement policy Karamanid Turks (mainly from the Konya Vilayet, Nevşehir Vilayet and Niğde Vilayet of the Karaman Province) were settled mainly in the Kardzhali area by the sultans Mehmed the Conqueror, Selim and Mahmud II. The Turkish community became an ethnic minority when the Principality of Bulgaria was established after the Russo-Turkish War of 1877–78. This community is of Turkish ethnic consciousness and differs from the majority Bulgarian ethnicity and the rest of the Bulgarian nation by its own language, religion, culture, customs, and traditions.

Islam in Bulgaria is a minority religion and the second largest religion in the country after Christianity. According to the 2021 Census, the total number of Muslims in Bulgaria stood at 638,708 corresponding to 9.8% of the population. Ethnically, Muslims in Bulgaria are Turks, Bulgarians and Roma, living mainly in parts of northeastern Bulgaria (mainly in Razgrad, Targovishte, Shumen and Silistra Provinces) and in the Rhodope Mountains (mainly in Kardzhali Province and Smolyan Province).

The tomb is probably the grave of Dromichaetes (Ancient Greek: Δρομιχαίτης, romanized: Dromichaites; c. 300 – c. 280 BC) who was a king of the Getae on both sides of the lower Danube (present day Romania and Bulgaria) around 300 BC, and his wife, the daughter of King Lysimachus (Greek: Λυσίμαχος, Lysimachos; c. 360 – 281 BCE) who was a general and diadochus (i.e., "successor") of Alexander the Great. The tomb is a UNESCO World Heritage Site.
