The official and institutional constitution of Caritas of Bishop's conference of Bosnia and Herzegovina can not be seen as a beginning of its work and act. The roots and the true meaning of the word Caritas have been tumbled in an act through many centuries in this region. In the year of 1931 the Archbishop of Vrhbosna Ivan Šarić established Caritas of Vrhbosna Archdiocese. Of course, this year has never meant the beginning of the work of the Catholic Church in Bosnia and Herzegovina. After the World War II and the communist governance, like many other the work of this institution was prohibited. Even in this difficult time the Church has found out a way to work. With the political changes at the beginning of the last decade of the 20th Century, the Church could again act in a wide sense, in organized and larger actions. Caritas of Mostar-Duvno and Trebinje-Mrkan diocese was established in 1982 by Bishop Pavao Žanić. And in the year of 1986 Bishop Franjo Komarica established Caritas of Banja Luka diocese. Caritas of Vrhbosna reestablished its public work in 1990. Necessity of existence of the institution of Caritas that would consolidate work of diocese was the reason to establish the Caritas of Bishop's conference of Bosnia and Herzegovina. Therefore, at the first assembly of Bishop's conference in Mostar, in January 1995, Caritas of Bishop’s conference in Bosnia and Herzegovina was established.
With the beginning of the war in Bosnia and Herzegovina, the situation became alarming and Caritas used al of it's recourses to find a way to help people affected by the war. The accent was made on refugees and displaced people who were left without their homes, socially affected, old and ill, wounded in war, families and persons without care, families with a several children, etc. In those days, fulfilled with hunger and cold, Caritas succeeded, in accordance with its abilities, to reach those in need. In a darkness of human dementia and lack of hope, Caritas was a light for surviving. On the other hand, Caritas's staff fought to reach those in need desolate all barriers. During the war period, Caritas's work has been based on saving lives. Huge quantities of food, clothes, medicine, and other things, were distributed to those in need. Thanks to Caritas's network in the World, we made it possible to distribute all the goods even in inaccessible places in Bosnia and Herzegovina.
Although it was a very difficult time, Caritas succeeded to initiate and realize social and health programs. A health center St. Vincent de Paule in Sarajevo began with work in November 1993. The primary health care, secondary health care, as well as the counseling for mental health, care for students and pharmacy have been organised in the Center. People living in the city, regardless of their nationality and religion used all services of the health center. In the year of 1993 Caritas opened an ambulance in Banja Luka. In the year of 1995 besides the ambulance for primary care, a surgery ambulance, eye audit, neuropsychiatry, dentist and ORL ambulance, laboratory and pharmacy were opened. During the war, Caritas also succeeded to organize a health projects in Mostar. Although the Caritas's building was completely destroyed in May 1993, Caritas in Mostar succeeded to keep warm ambience in a Social center, where a pharmacy and care for old and ill persons were situated.
