The Metropolitan area was reduced in the 1990s after the war and the Dayton-imposed administrative division of the country, with several municipalities partitioned along the border of the newly recognised Federation of Bosnia and Herzegovina (FBiH) and Republika Srpska (RS), creating several new municipalities which together form the city of Istočno Sarajevo in the Republika Srpska: Istočna Ilidza, Istočno Novo Sarajevo, Istočni Stari Grad, Lukavica, Pale (RS-section), and Trnovo (RS-section), along with the municipality of Sokolac (which was not traditionally part of the Sarajevo area and was not partitioned).
