Measurements of the area range from , or around 22% of the total area of the present-day country, to , around 24% of the country.
Herzegovina lobby
Proponents of the existence of such a lobby claim that it helped fund Croatia's war-time president Franjo Tuđman, his Croatian Democratic Union (HDZ) political party, and his involvement in the Bosnian War, during which the lobby openly advocated annexing Herzegovina. During the Bosnian War, Croats in Herzegovina, were more interested in unifying with Croatia than being a part of an independent Bosniak-dominated Bosnia and Herzegovina. Due to the strength of the Herzegovina lobby in Zagreb, moderate Bosnian Croats were mostly ineffective in influencing Croatian foreign policy on Bosnia and Herzegovina. Many extremists from Herzegovina served in the Croatian police force and to participate in skirmishes with Serbs. By late 1991 about 20,000 Croats in Bosnia and Herzegovina, mostly from the Herzegovina region, enlisted in the Croatian National Guard.
