The Baháʼí Faith in Bosnia and Herzegovina begins with mention by ʻAbdu'l-Bahá, then head of the religion, of Austria-Hungary which Bosnia and Herzegovina were part of at the time. Between the World Wars when Bosnia and Herzegovina were part of Yugoslavia, several members of Yugoslavian royalty had contact with prominent members of the religion. During the period of Communism in Yugoslavia, the first member of the Baháʼí Faith was in 1963 and the first Baháʼí Local Spiritual Assembly was formed in 1990. With the Yugoslavian civil war and separation into Bosnia and Herzegovina, the Baháʼís had not elected a Baháʼí National Spiritual Assembly but do have a small population in a few regions in the country.
Early days
Before 1918, the regions of Bosnia and Herzegovina were part of the Austrian-Hungarian Empire. ʻAbdu'l-Bahá, then head of the religion, wrote a series of letters, or tablets, to the members of the religion in the United States in 1916-1917; these letters were compiled together in the book Tablets of the Divine Plan. The seventh of the tablets mentioned European regions and was written on April 11, 1916, but was delayed in being presented in the United States until 1919—after the end of the First World War and the Spanish flu. The seventh tablet was translated and presented on April 4, 1919, and published in Star of the West magazine on December 12, 1919 and mentioned Austria-Hungary. He says:
"In brief, this world-consuming war has set such a conflagration to the hearts that no word can describe it. In all the countries of the world the longing for universal peace is taking possession of the consciousness of men. There is not a soul who does not yearn for concord and peace. A most wonderful state of receptivity is being realized.… Therefore, O ye believers of God! Show ye an effort and after this war spread ye the synopsis of the divine teachings in the British Isles, France, Germany, Austria-Hungary, Russia, Italy, Spain, Belgium, Switzerland, Norway, Sweden, Denmark, Holland, Portugal, Rumania, Serbia, Montenegro, Bulgaria, Greece, Andorra, Liechtenstein, Luxembourg, Monaco, San Marino, Balearic Isles, Corsica, Sardinia, Sicily, Crete, Malta, Iceland, Faroe Islands, Shetland Islands, Hebrides and Orkney Islands."
From 1918 to the 1990s Bosnia and Herzegovina were part of Yugoslavia. Before World War II Yugoslavia continued to be ruled by monarchs and among them there was awareness of the Baháʼí Faith. In July, 1938, Marie of Edinburgh, a member of the religion and Queen of Rumania, died. A message of condolence was communicated, in the name of all Baháʼí communities in East and West, to her daughter, Maria, then Queen of Yugoslavia, to which she replied expressing "sincere thanks to all of Baháʼu'lláh's followers." Later Princess Olga of Yugoslavia, on being informed of the death of Hand of the CauseMartha Root in 1939, remarked “She was so kind and gentle, and a real worker for peace. I am sure she will be sadly missed in her work.” Following the disruption of World War II and oppression during the early period of communism the first member of the Baháʼí Faith in Yugoslavia was an isolated Baháʼí in Belgrade who converted to the religion in 1963.
Growth
Since its inception the religion has had involvement in socio-economic development beginning by giving greater freedom to women, promulgating the promotion of female education as a priority concern, and that involvement was given practical expression by creating schools, agricultural coops, and clinics. The religion entered a new phase of activity when a message of the Universal House of Justice dated 20 October 1983 was released. Baháʼís were urged to seek out ways, compatible with the Baháʼí teachings, in which they could become involved in the social and economic development of the communities in which they lived. World-wide in 1979 there were 129 officially recognized Baháʼí socio-economic development projects. By 1987, the number of officially recognized development projects had increased to 1482. However in the Soviet Block the Baháʼís had all but disappeared. With the relaxation of the restrictions of Communism through Perestroyka, Yugoslavia's first Baháʼí Local Spiritual Assembly was established in November 1990 in Belgrade though the World Christian Encyclopedia maintained there were no Baháʼís in the country then. By 1998 Yugoslavia was torn by civil war and did not have a Baháʼí National Spiritual Assembly. Activities increased with a burgeoning community of Baháʼís. In 2001, Baháʼí youth gathered for a dance workshop in Zenica By 2003 Baháʼís had organized Bosnia and Herzegovina into 17 subregions, and four of these contained at least one Baháʼí and a few Ruhi Institutestudy circles were operating. Despite this, the Association of Religion Data Archives still estimated there were no Baháʼís in the country.
Modern community
The small community of Baha'is of Bosnia and Herzegovina has continued to have a presence in events beyond the confines of the country. In November 2004 membership of Baha'i inspired General Assembly of the International Environment Forum lists one member. In February 2008 the government of Bosnia and Herzegovina aligned themselves with the declaration of the President of Slovenia on behalf of the European Union on the deteriorating situation of the Baháʼís in Iran.
