In short: Proclaimed in 1991, the Croatian Republic of Herzeg-Bosnia functioned as a state within a state, maintaining its own currency, school curriculum, and military. Though formally abolished in 1996, its parallel institutions persisted for years, creating a complex legacy of governance, conflict, and deep ties to the Republic of Croatia.

The Croatian Community of Herzeg-Bosnia was established on 18 November 1991, initially framing itself as a temporary administrative entity. Its leadership, including figures like Mate Boban, sought to protect Croatian interests during the disintegration of Yugoslavia. While it officially recognized the government of Bosnia and Herzegovina, it operated with significant autonomy, eventually adopting the Croatian dinar as its currency and implementing a distinct school curriculum. By 1993, following the Owen-Stoltenberg peace proposal, it was declared a republic with its capital in Mostar and its administrative center in Grude.

The entity's existence was marked by intense volatility. Initially allied with Bosniak forces, the Croatian Defence Council (HVO) eventually engaged in the Croat–Bosniak War, a conflict fueled by shifting alliances and territorial disputes. The Hague Tribunal later ruled that Herzeg-Bosnia was part of a joint criminal enterprise aimed at creating a Croat-majority entity for eventual annexation by Croatia. This period saw the commission of grave crimes, including ethnic cleansing, leading to the indictment and conviction of several wartime leaders.

The 1994 Washington Agreement aimed to integrate Herzeg-Bosnia into a new Federation of Bosnia and Herzegovina, yet the entity continued to function until its formal abolition in 1996. Even after the Dayton Agreement ended the war, reports from the European Stability Initiative in 1999 revealed that parallel structures remained active. These institutions, including separate public utilities, financial bureaus, and social services, were heavily subsidized by the Croatian government. This created a situation where, in practice, parts of the region remained integrated with Croatia's military and economic systems long after the entity's official dissolution.

The economic reality of the region was equally complex. During the war, industrial production across Bosnia and Herzegovina plummeted by 80%. However, by 1995, Croat-majority areas saw a significant recovery, with industrial production growing by 25% and employment rising by 69% as the Croat-Bosniak alliance stabilized. Despite this growth, the reliance on parallel systems and external subsidies from Croatia underscored the persistent challenges of building a unified state in the aftermath of the conflict.
