Historical information
Pera (now Beyoğlu) 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 (Djem. II) and 24 Shawwal (Chev.) 1274, in 1858; the organisation of the central city in the city walls, "Stamboul" (), was not affected by these laws. All of Constantinople (all of which today is now Istanbul) was in the Prefecture of the City of Constantinople ().
