Ankara became Turkey's capital on October 13, 1923, when Mustafa Kemal Atatürk designated it as the seat of the new Turkish Republic. The city sits at 938 meters elevation on the Central Anatolia Plateau, approximately 450 kilometers southeast of Istanbul. The metropolitan area covers 25,632 square kilometers and had a population of 5,747,325 according to the 2023 Turkish Statistical Institute census. Ankara Province extends across central Anatolia with boundaries including Bolu to the north, Çankırı to the northeast, Kırıkkale to the east, Kırşehir to the southeast, Aksaray to the south, Konya to the southwest, and Eskişehir to the west.
The city occupies the historic region of Galatia, named for Celtic tribes who settled here in the third century BCE. The name Ankara derives from the ancient Greek Ankyra, meaning anchor, referenced in inscriptions from the Phrygian period. Romans conquered the settlement in 25 BCE and designated it capital of the province of Galatia. The Monumentum Ancyranum, located in the Ulus district, displays the Res Gestae Divi Augusti, a funerary inscription of Emperor Augustus carved on temple walls around 20 CE. This text records Augustus's achievements in both Latin and Greek, providing historians with details about Roman administrative practices in first-century Anatolia.
Byzantine Emperor Heraclius defeated Persian forces near Ankara in 622 CE during the Byzantine-Sasanian War. Seljuk Turks captured the city in 1073 following the Battle of Manzikert. Timur defeated Ottoman Sultan Bayezid I at the Battle of Ankara on July 20, 1402, temporarily fragmenting Ottoman territories. Ottoman forces recaptured Ankara in 1403 under Mehmed I. The city remained a provincial center within the Ottoman Empire for five centuries, known primarily for its Angora wool production from long-haired goats bred in the surrounding plateau.
Atatürk selected Ankara over Istanbul as capital for geographic and strategic considerations. The city's inland position provided distance from potential naval threats along the Bosphorus and Dardanelles. Rail connections linked Ankara to western and southern Anatolia through lines constructed during the Ottoman period. The Anatolian Railway reached Ankara in 1892, connecting the city to Istanbul via Eskişehir. During the Turkish War of Independence from 1919 to 1923, Ankara served as headquarters for the Turkish nationalist movement. The Grand National Assembly convened its first session in Ankara on April 23, 1920, establishing the legislative foundation for the republic.
German architect Hermann Jansen won the 1928 international competition to design Ankara's urban plan. Jansen's scheme organized the city into functional zones with the government quarter positioned on hills south of the old town. Austrian architect Clemens Holzmeister designed multiple government buildings between 1927 and 1943, including the first Grand National Assembly building completed in 1924. The current assembly complex opened in 1961 with a plenary hall seating 550 members. Italian architect Paolo Vietti-Violi designed Gençlik Park, completed in 1943, covering 28 hectares in the city center with an artificial lake and exhibition spaces.
Anıtkabir, the mausoleum of Mustafa Kemal Atatürk, stands on Anıttepe hill in the Çankaya district. Construction began in 1944 under architects Emin Onat and Ahmet Orhan Arda following a design competition. The complex opened on November 10, 1953, fifteen years after Atatürk's death. The main ceremonial plaza covers 75,000 square meters surrounded by colonnaded walkways. The Hall of Honor contains Atatürk's tomb beneath a ceiling reaching 17 meters high, supported by columns of red travertine quarried near Ankara. The surrounding museums display personal effects, documents, and vehicles used during Atatürk's presidency. The Turkish government designates November 10 as a national day of commemoration, with official ceremonies conducted at Anıtkabir at 09:05, the exact time of Atatürk's death in 1938.
The Museum of Anatolian Civilizations occupies a restored fifteenth-century bedesten and han in the Ulus district. The museum opened in 1921 as the Hittite Museum under Atatürk's directive.

The collection includes finds from Göbekli Tepe dating to 9500 BCE, statues from Çatalhöyük occupied between 7500 and 5700 BCE, and Hittite reliefs from Alacahöyük. Assyrian trader tablets from Kültepe, dating to approximately 1950 BCE, represent the oldest written documents found in Turkey, recording commercial transactions in cuneiform script. The European Museum of the Year Award recognized the institution in 1997.
Ankara Castle rises on a rocky outcrop 978 meters above sea level in the Ulus district. Archaeological evidence indicates fortifications existed here during Galatian occupation in the second century BCE. The inner citadel walls date to the seventh century CE under Byzantine Emperor Heraclius. Seljuk and Ottoman rulers modified and expanded the fortifications through the fourteenth century. The castle complex encloses an area of approximately 350 by 150 meters with 42 pentagonal towers spaced along walls reaching 14 to 16 meters high. The outer walls encompass the Hacı Bayram quarter, now a residential neighborhood with Ottoman-era houses built using traditional mudbrick and timber construction.
Hacı Bayram Mosque adjoins the Temple of Augustus in the Ulus district. Hacı Bayram Veli, founder of the Bayramiye Sufi order, commissioned the mosque's construction in 1427. The original structure followed early Ottoman architectural patterns with a single dome and square prayer hall. Architect Mimar Sinan renovated the building in 1562, adding exterior galleries and a portico. A türbe containing Hacı Bayram Veli's tomb stands adjacent to the mosque, attracting visitors who consider him a saint. Friday prayers regularly fill the mosque's capacity of approximately 2,000 worshippers.
Kocatepe Mosque, completed in 1987, represents modern Turkish religious architecture on a monumental scale. The structure occupies a prominent hill in the Kızılay district with four minarets reaching 88 meters high.

Construction costs exceeded 500 million Turkish lira funded through the Directorate of Religious Affairs and private donations.
Atatürk Forest Farm and Zoo opened in 1925 on 5,300 hectares of land Atatürk personally purchased and developed as an agricultural model farm. The property demonstrated modern farming techniques including dairy production, livestock breeding, and crop cultivation on previously barren land. The farm's dairy operation produced bottled milk distributed in Ankara beginning in 1926, one of Turkey's first commercial dairy operations. A brewery established on the grounds in 1937 continues to operate, producing Gazi beer named after Atatürk's honorific title. The zoo section closed in 2012, with animals transferred to other facilities. The remaining farm areas operate as public parkland with a museum displaying agricultural equipment from the 1920s.
