The Spanish soldiers based in Sarajevo contribute to the development of the Bosnian-Herzegovinian Armed Forces by advising them in terms of doctrine, interoperability, standardization and training. This will make them obtain the same capabilities and qualities as the rest of the NATO countries.
Currently, Spain is contributing to the Althea Operation with 3 soldiers, one of them in Mons (Belgium) and the other two in Sarajevo (Bosnia and Herzegovina).
On 25th January 2010, in the Council of the European Union, the member States agreed to transform the operation EUFOR Althea into a non-executive training and counselling Army mission.
The crisis originated in the Balkans in 1991, following splitting of the ex-Yugoslavia, which provoked some armed conflicts in Slovenia and Croatia. After the expansion of the war to Bosnia and Herzegovina, the UN started up an humanitarian aid mission in this country. In November 1992, Spain sent the first contingent, which was incorporated into the United Nations Protection Force (UNPROFOR), with the double aim of preserving compliance of the peace agreements achieved so far, as well as protecting humanitarian aid convoys.
At the end of that year, the confrontation between the Serbs and the coalition formed by Croatians and Muslims, fighting to take control of Bosnia and Herzegovina, was fiercely fought. At the beginning of 1993, Croatians and Muslims, until then allies, started to fight among themselves. In April, the war extended into the area assigned to Spanish forces in the Neretva valley, mainly Mostar, where the most violent combats were registered.
After the signing of the Dayton Agreements in Paris on 14 December 1995, which put an end to the war, NATO launched the IFOR mission, which replaced the Blue Helmets, and a year later, on 20 December 1996, the smaller SFOR. On 2 December 2004, SFOR gave way to EUFOR, an EU military operation, which on 25 October 2010 was transformed into a training and advisory mission for the Armed Forces of Bosnia and Herzegovina.
