The Posavina area was inhabited since prehistoric times, as evidenced by various archaeological finds of coins and other artifacts. After the 1718Treaty of Passarowitz between theOttoman Empire andHabsburg monarchy, mostly Catholic families from mountain villages were displaced across the plains, as the Turks themselves settled in the hills and valleys. The Croats fromŽupanja,Babina Greda andŠtitar moved to the villages ofKopanice,Vidovice,Tolisa andDomaljevac.
Before theBosnian War, the present-day municipalities ofDonji Žabar andVukosavlje belonged toOdžak andOrašje, while the present-day municipality ofDomaljevac-Šamac belonged toBosanski Šamac. The history of today's canton began on 18 March 1994 with the signing of theWashington Agreement. Posavina Canton was officially established on 12 June 1996 as one of the ten cantons of the Federation of Bosnia and Herzegovina, one of the 3 Croat-majority cantons.[2]
The canton lies near the border withCroatia and near the riverSava which forms a natural border between Bosnia and Herzegovina and Croatia. The canton consist of two unconnected exclaves: the western one consisting of Odžak municipality and the eastern one consisting of Orašje and Domaljevac-Šamac municipalities.
Posavina is a region which includes other parts of Bosnia and Herzegovina and parts of Croatia. Because of that, this canton is sometimes called Bosanska Posavina (Bosnian Posavina) and is the only part of northern Bosnia near the border with Croatia that lies in the Federation. The rest of northern Bosnia near the river Sava and near the border is theBrčko District and theRepublika Srpska. The Brčko district divides Republika Srpska into two parts.
The Posavina canton's position near the Sava river makes it a good place for agriculture because it is a flat lowland and there are no mountains in the area. It is like this in the entire northern border with Croatia, with a great deal of farming and agriculture. The river Sava is a river that flows through Slovenia, Croatia, Bosnia and Herzegovina and Serbia. In Bosnia and Herzegovina it flows through the northern border and makes a natural border between Bosnia and Herzegovina and Croatia.
Posavina means literally along Sava in the Bosnian language. The river Sava is the largest navigable river in Bosnia and Herzegovina. Much of the food in both Bosnia and Herzegovina and Croatia comes from this region, not only Bosnian Posavina but the rest of the fertile fields along the river Sava.
According to the law, Posavina Canton is one of the ten cantons of the Federation of Bosnia and Herzegovina, which is one of the two entities of Bosnia and Herzegovina.
Posavina has its ownlegislative,executive andjudicial powers. Like each of the cantons of FBiH, Canton Posavina has its ownconstitution,assembly,government, symbols and has a number of exclusive competences (police,education, use ofnatural resources, spatial andhousing policy,culture), while some competences are divided between federal and cantonal authorities (health, social protection,transport). The seat of the executive power, i.e. the capital of the canton, is Orašje (Posavina Cantonal Government), while in Domaljevac is the seat of the legislative power (Posavina Cantonal Assembly) and in Odžak is the seat of the judiciary.
At the local level, the citizens of Posavina Canton vote for the government in three municipalities every four years in free elections.
In the pre-war period, especially in the last ten years, the canton was one of the richest areas in Bosnia and Herzegovina. It is important in agriculture (Posavina is the largest granary in Bosnia and Herzegovina), economically (oil refinery in Bosanski Brod and Modriča, furniture, textiles, shoe factories, metal industry, chemical industry, etc.), river resources natural, forests, and the region is also known for the fact that many people did temporary jobs abroad. The area is oriented towards the West with convincing indicators of a very rapid integration into European cultural, economic and civilizational trends.
The majority of its population professesChristianity, with theCatholic Church being the most importantdenomination within the population with 33,191 inhabitants in the Canton of Posavina (representing more than 77 percent of the population). The most significant non-Christian minority is made up ofMuslims (8,341 inhabitants) and there are also other Christians such as members of theSerbian Orthodox Church (841 inhabitants).[8]
