Pera and Galata in the late 19th and early 20th centuries were a part of the Municipality of the Sixth Circle, established under the laws of 11 Jumada al-Thani and 24 Shawwal 1274, in 1858; the organisation of the central city in the city walls, "Stamboul", was not affected by these laws. All of Constantinople was in the Prefecture of the City of Constantinople.
