Oslo ( OZ-loh, also US: OSS-loh, Norwegian: [ˈʊ̂ʂlʊ] (listen), rarely [ˈʊ̂slʊ, ˈʊ̀ʂlʊ]) is the capital and most populous city of Norway. It constitutes both a county and a municipality. As of 23 November 2020, the municipality of Oslo had a population of 697,549, while the population of the city's greater urban area was 1,019,513, as of 4 November 2019. The metropolitan area had an estimated population of 1.71 million.During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in the year 1040 under the name Ánslo, and established as a kaupstad or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality (formannskapsdistrikt) on 1 January 1838. The city functioned as the capital of Norway during the 1814–1905 union between Sweden and Norway. From 1877, the city's name was spelled Kristiania in government usage, a spelling that was adopted by the municipal authorities only in 1897. In 1925, the city, after incorporating the village retaining its former name, was renamed Oslo. In 1948 Oslo merged with Aker, a municipality which surrounded the capital and which was 27 times larger, thus creating the modern, much larger Oslo municipality.
Oslo is the economic and governmental centre of Norway.

Istanbul ( ISS-tan-BUUL, also US: ISS-tan-buul; Turkish: İstanbul [isˈtanbuɫ] (listen)), formerly known as Byzantium and Constantinople, is the most populous city in Turkey and the country's economic, cultural and historical center. Istanbul is a transcontinental town in Eurasia, straddling the Bosporus strait (which separates Europe and Asia) between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives in suburbs on the Asian side of the Bosporus. With a total population of around fifteen million residents in its metropolitan area, Istanbul is one of the world's largest cities by population, standing as the world's fifteenth-largest town and the largest city in Europe. The town is the administrative center of the Istanbul Metropolitan Municipality (coterminous with Istanbul Province).
Founded under the name of Byzantion (Βυζάντιον) on the Sarayburnu promontory around 660 BCE, the city grew in size and influence, becoming one of the most significant cities in history. After its reestablishment as Constantinople in 330 CE, it served as an imperial capital for almost sixteen centuries, during the Roman/Byzantine (330--1204), Latin (1204--1261), Byzantine (1261--1453) and Ottoman (1453--1922) empires. It had been instrumental in the progress of Christianity during Roman and Byzantine times, before the Ottomans conquered the city in 1453 CE and transformed it into an Islamic stronghold and the seat of the Ottoman Caliphate. Under the name Constantinople it was the Ottoman capital until 1923. The capital was then moved to Ankara and the city was renamed Istanbul.
The town held the strategic position between the Black Sea and the Mediterranean.
