Blaž Kraljević was born on 19 September 1947 in the village of Lisice in the municipality of Ljubuški, in the People's Republic of Bosnia and Herzegovina.

[3] Kraljević was assigned to a select squad of HRB members who were training in Australia for an armed covert incursion into northern Yugoslavia in 1972.

This squad, known as the Bugojno group, entered Yugoslavia but failed in its mission, with 18 of the 19 men involved being either killed or executed by Yugoslav forces.

[4] Kraljević resided in Kambah, an outer suburb of Canberra and worked as a bricklayer, but continued to be an active proponent of Croatian nationalism.

He became a leading spokesman for the Australian branch of the Croatian National Council, an organisation lobbying for the destruction of Yugoslavia through whatever means necessary.

He was also active in public protests against Yugoslavia, being arrested in 1978 for throwing bottles of red paint at the Yugoslav embassy in Canberra.

[8] In 1990 and 1991, Serb militias in Croatia and in Bosnia and Herzegovina, armed by and acting in concert with the well-equipped Yugoslav People's Army (JNA), seized large territories.

[13] In November 1991, the autonomous Croatian Community of Herzeg-Bosnia (HZ-HB) was established, it claimed that it did not aim to secede and that it would serve a "legal basis for local self-administration" within the framework of Bosnia and Herzegovina, but not Yugoslavia.

[11] On 15 April 1992, the multi-ethnic Army of the Republic of Bosnia and Herzegovina (ARBiH) was formed, with slightly over two-thirds of troops consisting of Bosniaks and almost one-third of Croats and Serbs.

"[8] Kraljević commented on the internal divisions of Croats and closed stating "We will get rid of the people with a dark past and suspicious present.

Božidar Vučurević, the war-time mayor of Trebinje, stated he safeguarded records showing it was a "task" to be carried out by SDS and HDZ figures.

[35] The HOS's advance into eastern Herzegovina and occupation of Trebinje angered Boban who had affirmed to Karadžić that Croat forces were uninterested in the region.

[19] After his death, Croatian media claimed Kraljević was an agent of the UDBA, Yugoslav secret police, who had returned from Australia to harm the interests of Bosnian Croats.

[12] In 1996, at the insistence of Šušak, Tuđman posthumously awarded Kraljević the Order of Petar Zrinski and Fran Krsto Frankopan.
