Istanbul (/ˌɪstænˈbʊl/ IST-an-BUUL, US also /ˈɪstænbʊl/ IST-an-buul; Turkish: İstanbul [isˈtanbuɫ] (listen)), formerly known as Constantinople, is the largest city in Turkey, serving as the country’s economic, cultural and historic hub. The city straddles the Bosporus strait, lying in both Europe and Asia, and has a population of over 15 million residents, comprising 19% of the population of Turkey. Istanbul is the most populous European city,[b] and the world’s 15th-largest city.
The city was founded as Byzantium (Byzantion) in the 7th century BCE by Greek settlers from Megara. In 330 CE, the Roman emperor Constantine the Great made it his imperial capital, renaming it first as New Rome (Nova Roma) and then as Constantinople (Constantinopolis) after himself. The city grew in size and influence, eventually becoming a beacon of the Silk Road and one of the most important cities in history.
Travel is the movement of people between relatively distant geographical locations, and can involve travel by foot, bicycle, automobile, train, boat, bus, airplane, or other means, with or without luggage, and can be one way or round trip. Travel can also include relatively short stays between successive movements.
The origin of the word “travel” is most likely lost to history. The term “travel” may originate from the Old French word travail, which means ‘work’. According to the Merriam Webster dictionary, the first known use of the word travel was in the 14th century.
It also states that the word comes from Middle English travailen, travelen (which means to torment, labor, strive, journey) and earlier from Old French travailler (which means to work strenuously, toil). In English we still occasionally use the words “travail”, which means struggle. According to Simon Winchester in his book The Best Travelers’ Tales (2004), the words “travel” and “travail” both share an even more ancient root: a Roman instrument of torture called the tripalium (in Latin it means “three stakes”, as in to impale).
