The Bosnian War, which was fought between Bosnia and Herzegovina, Croatia, and Serbia, attracted large numbers of foreign fighters and mercenaries from various countries. Volunteers came to fight for a variety of reasons including religious or ethnic loyalties and in some cases for money. As a general rule, Bosniaks received support from Islamic countries, Serbs from Eastern Orthodox countries, and Croats from Catholic countries. The presence of foreign fighters is well documented, however none of these groups comprised more than 5 percent of any of the respective armies' total manpower strength.
