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.
Singapore ( (listen)), officially the Republic of Singapore, is a sovereign island city-state in maritime Southeast Asia. It lies about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Straits of Malacca to the west, the Riau Islands to the south, and the South China Sea to the east. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet, the combined area of which has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the second greatest population density in the world. The country is home to almost 5.7 million residents, 61% (3.4 million) of whom are Singaporean citizens. There are four official languages of Singapore: English, Malay, Chinese, and Tamil; with English being the lingua franca. Multiracialism is enshrined in the constitution, and continues to shape national policies in education, housing, and politics.
Although its history stretches back millennia, modern Singapore was founded in 1819 by Sir Stamford Raffles as a trading post of the British Empire. In 1867, the colonies in East Asia were reorganised and Singapore came under the direct control of Britain as part of the Straits Settlements. During the Second World War, Singapore was occupied by Japan in 1942, but returned to British control as a separate crown colony following Japan's surrender in 1945. Singapore gained self-governance in 1959, and in 1963 became part of the new federation of Malaysia, alongside Malaya, North Borneo, and Sarawak. Ideological differences led to Singapore being expelled from the federation two years later, thereby becoming an independent country. Since then, Singapore is considered the only fully sovereign city-state in the world, with its own currency and technologically advanced military forces.
After early years of turbulence and despite lacking natural resources and a hinterland, the nation rapidly developed to become one of the Four Asian Tigers based on external trade, becoming the highest developed country in Asia.
