Niğde in the context of "Niğde Province"

Aksaray Province (Turkish: Aksaray ili) is a province in central Turkey. Its adjacent provinces are Konya along the west and south, Ankara to the northwest, Niğde to the southeast, Nevşehir to the east, and Kırşehir to the north. Its area is 7,659 km, and its population is 439.474 (2022). The provincial capital is the city of Aksaray.

Aksaray is one of the four provinces in Cappadocia, along with Nevşehir, Niğde, and Kayseri. Also, the 3,000-metre (9,843 ft) volcano Mount Hasan stands between Aksaray and Niğde. Summers are hot and dry on the plain, but the area is green and covered in flowers in springtime, when water streams off the mountainside. The 2,400 m2 salt lake (0.59 acres), Tuz Gölü, lies within the boundaries of Aksaray, a large swamp area with a maximum depth of 1 metre (3 ft 3 in).

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.

Niğde District (also: Merkez, meaning "central" in Turkish) is a district of the Niğde Province of Turkey. Its seat is the city of Niğde. Its area is 2,223 km, and its population is 236,793 (2022).

Otoyol 4 (English: Motorway 4), named Anatolian Motorway (Turkish: Anadolu Otoyolu) and abbreviated as O-4, is a toll motorway connecting the northwestern Marmara region to the Central Anatolia Region in Turkey. It runs parallel to the D.100 for more than half of its length and then parallels the D750 for most of the eastern half. The O-4 is a major expressway in Turkey as it connects eastern Istanbul and the heavily urbanized northeastern shore of the Sea of Marmara to the nation's capital, Ankara. The O-4 also makes up part of the International E-road network E80 and E89 as well as the AH-1 of the Asian Highway Network.

The O-4 is the longest completed motorway in Turkey spanning 379 km (235 mi), just 14 km (8.7 mi) longer than the O-52. The partially-opened O-5 is expected to surpass the length of the O-4, when it is completed in 2019, with a total length of 407 km (253 mi). but nowadays the longest motorway in Turkey is Otoyol 21 with the opening Ankara-Niğde section. Construction of the O-4 began in 1984 and was widely completed in 1992 except for a short gap through the mountains west of Bolu. This gap was connected in 2006, with the opening of the Mount Bolu Tunnel.
