Budapest (, Hungarian pronunciation: [ˈbudɒpɛʃt]) is the capital and the most populous city of Hungary, and the ninth-largest city in the European Union by population within city limits. The city has an estimated population of 1,752,286 over a land area of about 525 square kilometres (203 square miles). Budapest is both a city and county, and forms the centre of the Budapest metropolitan area, which has an area of 7,626 square kilometres (2,944 square miles) and a population of 3,303,786, comprising 33% of the population of Hungary.The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century, but the area was pillaged by the Mongols in 1241–42. Re-established Buda became one of the centres of Renaissance humanist culture by the 15th century.
The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the region entered a new age of prosperity, with Pest-Buda becoming a global city after the unification of Buda, Óbuda, and Pest on 17 November 1873, with the name 'Budapest' given to the new capital. Budapest also became the co-capital of the Austro-Hungarian Empire, a great power that dissolved in 1918, following World War I. The city was the focal point of the Hungarian Revolution of 1848, the Battle of Budapest in 1945, and the Hungarian Revolution of 1956.Budapest is a Beta + global city with strengths in commerce, finance, media, art, fashion, research, technology, education, and entertainment.
Ankara ( ANK-ə-rə, also US: AHNK-ə-rə, Turkish: [ˈaŋkaɾa] (listen)), historically known as Ancyra ( an-SY-rə) and Angora ( ang-GOR-ə, also US: ANG-gə-rə), is the capital of Turkey. Located in the central part of Anatolia, the city has a population of 4.5 million in its urban center and over 5.6 million in Ankara Province, making it Turkey's second-largest city after Istanbul.
Serving as the capital of the early Celtic country of Galatia (280--64 BC), and later of the Roman province with the identical name (25 BC--7th century), the city is very old with various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archaeological sites. The Ottomans made the city the capital first of the Anatolia Eyalet (1393--late 15th century), and the Angora Vilayet (1867--1922). The historic center of Ankara is a rocky mountain climbing 150 m (500 ft) over the left bank of the Ankara River, a tributary of the Sakarya River. The hill remains crowned by the ruins of Ankara Castle. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture across the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the Res Gestae Divi Augusti.
