Istanbul Province (Turkish: İstanbul ili) is a province located in north-west Turkey. It has an area of 5,196 km² and a population of 13,255,685. The population was 10,018,735 in 2000. It is surrounded by the provinces of Tekirdağ to the west, Kocaeli to the east, the Black Sea to the northern part and the Sea of Marmara to the south. The Bosphorus (Boğaziçi) Strait divides the province in two parts: the European side and the Asian side. Roughly 3.85 million people live on the Asian side in 2010 census, and 9.4 million on the European side.

The capital of the province is the city of Istanbul, which, since 2004, has the same boundaries as the province.

The province also includes the Princes' Islands constituted as Adalar District (Island District).

Istanbul (Turkish: İstanbul) is the largest city in Turkey, forming the country's economic, cultural, and historical heart. With a population of 13.4 million, the city is at the center of the second-largest urban area in Europe after Moscow, and among the world's largest cities by population within city limits. Istanbul's vast area of 5,343 square kilometers (2,063 sq mi) is coterminous with Istanbul Province, of which the city is considered capital. Straddling the Bosphorus—one of the world's busiest waterways—in northwestern Turkey, between the Sea of Marmara and the Black Sea, Istanbul is a transcontinental city, with one third of its population living in Asia but its commercial and historical center in Europe.

Founded around 660 BC as Byzantium on the Seraglio Point, the city now known as Istanbul developed to become one of the most significant cities in history. For nearly sixteen centuries following its reestablishment as Constantinople in 330 AD, it served as the capital of four empires — the late classical Roman Empire (330–395), the Eastern Roman ("Byzantine") Empire (395–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). It was instrumental in the advancement of Christianity during Roman and Byzantine times, before the Ottomans conquered the city in 1453 and transformed it into an Islamic stronghold from which the last caliphate ruled. Although the Republic of Turkey established its capital elsewhere, in Ankara, remnants of Istanbul's previous central role still remain highly visible across the city, with palaces and imperial mosques lining its hills.

Pierre Loti (pseudonym of Julien Viaud; 14 January 1850 – 10 June 1923) was a French novelist and naval officer.

Loti's education began in his birthplace, Rochefort, Charente-Maritime. At the age of seventeen he entered the naval school in Brest and studied at Le Borda. He gradually rose in his profession, attaining the rank of captain in 1906. In January 1910 he went on the reserve list. He was in the habit of claiming that he never read books, saying to the Académie française on the day of his introduction (7 April 1892), "Loti ne sait pas lire" ("Loti doesn't know how to read"), but testimony from friends proves otherwise, as does his library, much of which is preserved in his house in Rochefort. In 1876 fellow naval officers persuaded him to turn into a novel passages in his diary dealing with some curious experiences at Istanbul. The result was the anonymously published Aziyadé (1879), part romance, part autobiography, like the work of his admirer, Marcel Proust, after him.

He proceeded to the South Seas as part of his naval training, and several years after leaving Tahiti published the Polynesian idyll originally named Rarahu (1880), which was reprinted as Le Mariage de Loti, the first book to introduce him to the wider public. His narrator explains that the name Loti was bestowed on him by the natives, after a red flower. The book inspired the 1883 opera Lakmé by Léo Delibes.
