On 21 July 1992, Bosnia and Herzegovina and Croatia sign the Agreement on Friendship and Cooperation — the bilateral instrument from the start of the Yugoslav wars fixing mutual recognition and political cooperation.

Signed amid BiH independence and the conflict with Serb forces, it pursues a Zagreb–Sarajevo alliance against aggressors and diplomatic coordination.

The military context remained tense (including later Croat–Bosniak clashes), but the document marks a formal friendship commitment between the two independent republics.

It belongs to the 1990s series of bilateral treaties redrawing the map of Yugoslav successor states.

For Balkan diplomacy, 21 July 1992 marks the signing of the Bosnia–Croatia friendship agreement.

The text is documented in diplomatic collections and Bosnia war historiography.

The Bosnia–Croatia friendship agreement of 21 July 1992 remains the milestone of bilateral relations at the start of independence.
