The Municipality of Bucharest (the capital of Romania) is divided into six administrative units, named sectors (sectoare in Romanian), each of which has their own mayor and council, and has responsibility over local affairs, such as secondary streets, parks, schools and the cleaning services.
Each of the six sectors contains a number of informal districts (cartiere) which have no administrative function:
Initially, Bucharest was divided into plăși. In 1798, there were five of these: Târgul, Podul Mogoșoaiei, Târgul de afară, Broștenii and Gorganul. During the Russo-Turkish War (1806-1812), these were given the names of colors (Roșu - Red; Galben - Yellow; Negru - Black; Albastru - Blue and Verde - Green) and called culori ("colors"). Roșu, the smallest, composed of the commercial center and a narrow strip on the right bank of the Dâmbovița River, was disbanded at the beginning of the 20th century, its territory divided among the other four. After World War I, each of the four culori, also called sectoare by this time, was given its own mayor and council. At the beginning of Ion Antonescu's regime, the culori were briefly abolished but restored several months later.
In 1950, soon after the onset of the Communist regime, the culori were abolished and replaced by eight raions, each with its own local administration: Grivița Roșie (1), 30 Decembrie (2), 1 Mai (3), 23 August (4), Tudor Vladimirescu (5), Nicolae Bălcescu (6), V.I. Lenin (7) and 16 Februarie (8). In 1968, the raions became sectors, their names replaced by cardinal numbers. In 1979, Sector VIII was merged into Sector I and Sector II into Sector 3, yielding the present six sectors.
