Eastern Slavonia, Baranja and Western Syrmia (Serbian:Источна Славонија, Барања и Западни Срем,romanized: Istočna Slavonija, Baranja i Zapadni Srem;Croatian:Istočna Slavonija, Baranja i Zapadni Srijem), commonly abbreviated asEastern Slavonia (Serbian:Источна Славонија,romanized: Istočna Slavonija;Croatian:Istočna Slavonija), was a short-livedSerb parallel entity in the territory ofCroatia along theDanube river.

The entity encompassed the same territory as theSAO Eastern Slavonia, Baranja and Western Syrmia, which was formed in 1991, and was anexclave had been merged into the self-proclaimedRepublic of Serbian Krajina. When the latter entity was defeated at the end of theCroatian War of Independence in 1995, the territory of Eastern Slavonia remained in place for another three years in which it experienced significant changes ultimately leading to peaceful reintegration via theUnited Nations Transitional Administration for Eastern Slavonia, Baranja and Western Sirmium (UNTAES).

In the period between August 1995 and January 1996, the region functioned as arump territory of the Republic of Serbian Krajina. The period was marked by increased insecurity and expectation of the Croatian military offensive. A diplomatic solution that avoided the conflict in Eastern Slavonia was reached on 12 November 1995^[3] via the signing of theErdut Agreement with significant support and facilitation from theinternational community (primarily theUnited States,^[4] theUnited Nations,^[5] and variousEuropean actors).^[6]

As the result of the fact that the UNTAES became the effective government of the region, from January 1996 onwards local parallel institutions of the Eastern Slavonia, Baranja and Western Syrmia started functioning primarily as theconsociational representative institutions of the Serb community in the region. As such, they were acknowledged and involved in elaborate power-sharing initiatives by the UNTAES, yet they were gradually abolished as the local Serb community got exponentially more integrated and involved inpower-sharing in regular mainstream institutions of the Croatian state/society. At the same time, Croat and otherrefugees from the region and Croatian institutions gradually returned to the region. Croatian state officials were welcomed to the region by the UNTAES administration including at the time of the first visit by thePresident of CroatiaFranjo Tuđman in late 1996 when the head of the UNTAESJacques Paul Klein organized a meeting between Croat and Serb delegation at the UNTAES headquarters inVukovar.^[7]

With the abolition of the parallel Serb bodies of the Eastern Slavonia, Baranja and Western Syrmia, the local Serb community began to exercise its right to establish regular institutions and bodies of cultural self-government. The main one of them was theJoint Council of Municipalities, an elected consultativesui generis inter-municipal body created to advocate for the interests of theSerb community in the region.^[8] This process was consequential for the rest of Croatia as well as it enabled the creation of other statewide bodies such as theSerb National Council. International community remained present in the region primarily inobservers capacity via theUnited Nations Civilian Police Support Group (16 January 1998–15 October 1998) andOSCE Mission to Croatia (1996–2007).

Eastern Slavonia, Baranja, and Western Syrmia was formed out of the only part of the rebelRepublic of Serbian Krajina that was not overrun byCroatian government forces in August 1995. AfterOperation Storm in August 1995, by which the majority of the Republic of Serbian Krajina was restored to Croatian control, Eastern Slavonia, Baranja and Western Syrmia became ade facto self-governing territory. Immediately upon completion ofOperation Storm,U.S. PresidentBill Clinton, within the framework of an initiative to end the war in Bosnia, said that:^[9]

"There must be a long-term plan for a sustainable solution to the situation in Eastern Slavonia ... based on Croatian sovereignty and the principles outlined in the Z-4 plan."

Croatia in this period hesitated between a diplomatic or military solution, but due to strong pressure from the international community, the possibility of military intervention was rejected.^[10] In November 1995, local Serb leaders signed theErdut Agreement, by which the eventual re-integration of this region into Croatia was agreed-upon.^[10] The Erdut agreement was reached as part of negotiations at theDayton Agreement conference. Nevertheless, the Croatian negotiating team rejected theZ-4 plan proposed by Bill Clinton as a basis for negotiations.^[10]

By theErdut Agreement, Eastern Slavonia, Baranja and Western Syrmia was replaced by theUnited Nations Transitional Administration for Eastern Slavonia, Baranja and Western Sirmium on 15 January 1996. The goal of the UNTAES mission was the creation of a transitional period during which the UNTAES peacekeepers would oversee a peaceful reintegration of the territory into Croatia. During the 1995–1998 period, the territory was called "Danube Krajina" (PodunavskaKrajina) bySerbs, and "Croatian Danube" or "Croatian Podunavlje" (Hrvatsko Podunavlje) byCroats. The name often used for it between 1995 and 1998 was Syrmia-Baranja Oblast. Sometimes, the shortened name Eastern Slavonia was also used as a designation for this region.^[10]

Within the framework of reintegration in 1996 and under pressure from the international community, an abolition decision was passed for those who participated in rebellion.^[10] One of the main tasks for the new United Nations mission was to create conditions for the return ofCroats who were expelled during the war in this region. They also sought to avoid a new wave of emigration of the ethnic Serb community to Serbia that was seen afterOperation Storm.

In 1996, all the towns and municipalities in the region were designatedAreas of Special State Concern by the Croatian government. In 1998, the UNTAES mission was completed and the territory was formally integrated into Croatia.

AfterOperation Flash, representatives ofRepublika Srpska andRepublic of Serbian Krajina announced that they would implement unification of these two entities.^[11] In response to this, local Serb leaders in Eastern Slavonia, Baranja and Western Syrmia founded a body called theCoordinating Committee that opposed unification, arguing that it would just deepen the crisis and damage Belgrade's intentions to achieve peace in Bosnia.^[11] Authorities of the RSK inKnin declared the goal of theCoordinating Committee to be thesecession of Eastern Slavonia, Baranja and Western Syrmia from Republic of Serbian Krajina, claiming that there is now no power in Knin, but instead in Belgrade.^[11] This statement became a reality onceOperation Storm was completed because western parts of Republic of Serbian Krajina no longer existed. During the Croatian military actions Flash and Storm on western parts of Krajina, the army in Eastern Slavonia did not act against theCroatian Army.^[11] However, local Serbs representatives strongly condemned the actions of the Croatian Army. After these events, and institution was established that was called theNational Council Syrmia-Baranja Oblast and the region's name was changed toSyrmia-Baranja Oblast.^[11] Since the region was keen to maintain continuity with the Republic of Serbian Krajina for future negotiations, the region also established theNational Council of Republic of Serbian Krajina of Syrmia-Baranja Oblast.^[11] In 1996 inIlok, there was a proposal to abolish the District Assembly because there were no conditions for its work, but this proposal was rejected.^[11] The District Assembly was a body with 50 members elected in elections. In 1997 in Vukovar, theIndependent Democratic Serb Party was established.^[12] That same year, theJoint Council of Municipalities was founded, and by the end of reintegration, all the other entities were abolished and replaced by Croatian institutions.^[8]

The local Serb population did not regard the plans to reunite the region with Croatia with approval. At the end of June 1996, NGOs in the region organized a petition that asked that the region remain a special area with independent executive, legislative and judiciary. The petition was signed by 50,000 residents of Eastern Slavonia, Baranja and Western Syrmia.^[11] The petition was then sent to theUnited Nations.^[11] In 1997 in Vukovar, protests were organized in which the local population called for the establishment of autonomous Serbian institutions after the completion of reintegration. The protests gathered between 5,000 and 12,000 participants. At the protests, protesters expressed opposition to the partition of the region in two Croatian counties (Vukovar-Syrmia County andOsijek-Baranja). That question was posed in the1997 Eastern Slavonia integrity referendum in which, according to the Electoral Commission, the voter turnout was 77.40%. Reportedly 99.01% or 99.5% of voters voted for the integrity of the region within Croatia.^[13] Nonetheless, it did not prevent the decision and the region was divided. Representatives of United Nations missions in the region said that the referendum was irrelevant because such an option was never considered.^[14]

The majority of ethnic Croats from Eastern Slavonia, Baranja and Western Syrmia were expelled from the region in conflicts in the early nineties. The persecution of 150 locals ofĆelije in the village ofTrpinja municipality in July 1991 was the first mass exodus of the population in the Croatian War.^[1] Although one of the tasks of the first United Nations missionUNPROFOR was to create conditions for the return of refugees, little had been done on that issue before signingErdut Agreement. This prompted refugees to organize themselves in new communities in Croatia. These refugees from the region that are now living in Croatia organized regional clubs, refugee organizations and exhibitions.^[10] In addition, newspapers and other publications were published in other parts of Croatia, which included Vukovarske Novine, HrvatskiTovarnik,Iločki list, Lovaski list, Baranjske novine, Vukovarac and ZovSrijema.^[10] There also were organized protests againstUNPROFOR and blockades of official UNPROFOR crossings between region and Croatia.^[10] By the end of UNTAES mandate, only two Catholic churches in region still were in regular function.^[15]

Upon the completion of the reintegration of the region and UNTAES departure the newUnited Nations Civilian Police Support Group (UNPSG) was deployed to the region from 16 January 1998 to 15 October 1998.^[16] Up until 2007 theOSCE Mission to Croatia remained active in the country with a focus on the region which was under the UNTAES control. The mission provided the Police Monitoring Group for the region in the 1998-2000 period.^[17] TheJoint Council of Municipalities was established as one of the central institutions in the region yet it was in no way legally linked as a successor to the Eastern Slavonia, Baranja and Western Syrmia. In the former administrative centre and the largest town ofVukovar, theconsulate general of the Republic of Serbia was opened in 1998. A large number of Serbian minority institutions in the area were established or continued to work, such as theEparchy of Osječko polje and Baranja,Radio Borovo, theAssociation for Serbian language and literature in the Republic of Croatia, theIndependent Democratic Serb Party, and others.Croatia andSerbia still have open border disputes in this area around the two islands on theDanube – theIsland of Vukovar and theIsland of Šarengrad.

The territory of former Eastern Slavonia, Baranja and Western Syrmia is part of the Central EuropeanPannonian Basin. The eastern border of the region was mostly theDanube river, while approximately one third of the western border was theDrava river. TheKopački rit natural preserve was located near the confluence of Drava and Danube, and it formed a major geographical barrier – there were no road or rail connections between Baranja and the southern parts of the territory, except through Serbia.

Other boundaries were not natural boundaries: the border withHungary in the north had existed since theKingdom of Serbs, Croats and Slovenes, the eastern border withFR Yugoslavia partly existed since theKingdom of Slavonia (on the Danube) and was partly set with the formation ofSFR Yugoslavia, while the border with the rest ofCroatia in the west and south was formed after the fronts were settled in the first phase of theCroatian War of Independence.

Eastern Slavonia, Baranja and Western Syrmia on its territory had 124 settlements, and with its 193,510 inhabitants, it was the largestSerbian Autonomous Oblast by population created on the territory of Croatia.^[1] Eastern Slavonia is a mostly flat area, with the best type of soil where agriculture is highly developed, particularly on wheat fields. It also has several forests as well as vineyards. The Đeletovci Oil Fields are located between the villages ofĐeletovci,Banovci andNijemci.

Traffic over theBrotherhood and Unity Highway (today theA3) was interrupted with the formation of the ESBWS. The water transport over theDanube river continued unobstructed. TheDrava river was not navigated at the time. The railway line betweenZagreb andBelgrade and the transport betweenBudapest andSarajevo were also closed.
