Bosanska Krupa (Serbian Cyrillic: Босанска Крупа) is a city located in the Una-Sana Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina. As of 2013, it has a population of 29,659 inhabitants.

It is situated on the banks of river Una in northwestern Bosnia and Herzegovina, 30 km (19 mi) northeast from Bihać (350 km away from Sarajevo).

The Una (Serbian Cyrillic: Уна, pronounced [ûna]) is a border river between Bosnia and Herzegovina and Croatia and a right tributary of the Sava river. It is part of the Black Sea drainage basin, and its watershed has a size of 10,200 km (3,900 sq mi), of which 8,080 km (3,120 sq mi) belongs to Bosnia and Herzegovina, and 2,120 km (820 sq mi) to Croatia. The total length of the river is 212 km (132 mi). The source of the river is located near the village of Donja Suvaja in Croatia, and its mouth is located near the village of Jasenovac, on the border with Bosnia. The largest right tributaries are the Krka, Unac, Krušnica and Sana rivers, and the largest left tributary is the Klokot river. Its longest headwater is the Unac river. The largest and most important city located on the river is Bihać. Other, important cities and towns are Bosanska Krupa, Bosanski Novi and Bosanska Kostajnica. The river is characterized by a multitude of waterfalls, rapids, karst springs and relatively untouched nature. A large part of the upper river is part of the Una National Park.

The Anti-Fascist Council for the National Liberation of Yugoslavia, commonly abbreviated as the AVNOJ, was a deliberative and legislative body that was established in Bihać, Yugoslavia, in November 1942. It was established by Josip Broz Tito, the leader of the Yugoslav Partisans, an armed resistance movement led by the Communist Party of Yugoslavia to resist the Axis occupation of the country during World War II.

The AVNOJ reconvened in Jajce in 1943 and in Belgrade in 1945, shortly after the war in Europe ended. Between the sessions, it operated through its presidency, its executive council, and the National Committee for the Liberation of Yugoslavia. The committee was granted authority normally wielded by cabinets. While Tito presided over the committee, the AVNOJ sessions and its presidency were chaired by Ivan Ribar. The second session of the AVNOJ proclaimed itself Yugoslavia's new legislative body and decided that it should be a multi-ethnic federal state.

The Long Turkish War, or Thirteen Years' War, was an indecisive land war between the Holy Roman Empire (primarily the Habsburg monarchy) and the Ottoman Empire, primarily over the principalities of Wallachia, Transylvania, and Moldavia. It was waged from 1593 to 1606, but in Europe, especially in Hungary, it is called the Fifteen Years' War (Hungarian: tizenöt éves háború), reckoning from the 1591–1592 Turkish campaign that captured Bihać in the Kingdom of Croatia. In Turkey, it is called the Ottoman–Austrian War of 1593–1606 (Turkish: 1593–1606 Osmanlı-Avusturya Savaşı).

In the series of Ottoman wars in Europe, it was the major test of force in the time period between the Ottoman–Venetian War (1570–1573) and the Cretan War (1645–1669). The next of the major Ottoman–Habsburg wars was that of 1663–1664. Though the conflict featured a large number of costly battles and sieges, it produced little gain for either side.

The Una-Sana Canton (Bosnian: Unsko-sanski kanton; Croatian: Unsko-sanska županija; Serbian: Унско-сански кантон, romanized: Unsko-sanski kanton) is a federated state and one of the ten cantons of the Federation of Bosnia and Herzegovina in Bosnia and Herzegovina. It is located in the northwest of the country, a region known as Bosanska Krajina, and has been named after the rivers Una and Sana. Its cantonal seat is the city of Bihać.

The canton is bordered by Republika Srpska from the east, the Canton 10 from the southeast, and Croatia from the south, west, and north. The majority of the population is Bosniak (90%).

The Croat–Bosniak War or Croat–Muslim War was a conflict between the Bosniak-dominated Republic of Bosnia and Herzegovina and the Croatian Republic of Herzeg-Bosnia, supported by Croatia, that lasted from 18 October 1992 to 23 February 1994.It is often referred to as a "war within a war" because it was part of the larger Bosnian War. In the beginning, the Army of the Republic of Bosnia and Herzegovina (ARBiH) and the Croatian Defence Council (HVO) fought together in an alliance against the Yugoslav People's Army (JNA) and the Army of Republika Srpska (VRS). By the end of 1992, however, tensions between the ARBiH and the HVO increased. The first armed incidents between them occurred in October 1992 in central Bosnia. The military alliance continued until early 1993, when it mostly fell apart and the two former allies engaged in open conflict.

The Croat–Bosniak War escalated in central Bosnia and soon spread to Herzegovina, with most of the fighting taking place in those two regions. The war generally consisted of sporadic conflicts with numerous short ceasefires. However, it was not an all-out war between Bosniaks and Croats and they remained allied in other regions – mainly Bihać, Sarajevo and Tešanj. Several peace plans were proposed by the international community during the war, but each of them failed. On 23 February 1994, a lasting ceasefire was agreed, and an agreement ending the hostilities was signed in Washington on 18 March 1994, by which time the HVO had suffered significant territorial losses. The agreement led to the establishment of the Federation of Bosnia and Herzegovina and the resumption of joint operations against Serb forces, which helped alter the military balance and bring the Bosnian War to an end.

The Battle of Sisak was fought on 22 June 1593 between Ottoman Bosnian forces and a combined Christian army from the Habsburg lands, mainly the Kingdom of Croatia and Inner Austria. The battle took place at Sisak, central Croatia, at the confluence of the Sava and Kupa rivers, on the borderland between Christian Europe and the Ottoman Empire.

Between 1591 and 1593 the Ottoman military governor of Bosnia, Beglerbeg Telli Hasan Pasha, attempted twice to capture the fortress of Sisak, one of the garrisoned castles that the Habsburgs maintained in Croatia as part of the Military Frontier. In 1592, after the key imperial fortress of Bihać fell to the Turks, only Sisak stood in the way before Croatia's main city Zagreb. Pope Clement VIII called for a Christian league against the Ottomans, and the Sabor recruited in anticipation a force of about 5,000 professional soldiers.

Bosanska Krajina (Serbian Cyrillic: Босанска Крајина, pronounced [bɔ̌sanskaː krâjina], lit. 'Bosnian Frontier') is a geographical region, a subregion of Bosnia, in western Bosnia and Herzegovina. It is enclosed by several rivers, namely the Sava (north), Glina (northwest), Vrbanja and Vrbas (east and southeast, respectively). The region is also a historic, economic, and cultural entity of Bosnia and Herzegovina, noted for its preserved nature and wildlife diversity.

The largest city and historical center of the region is Banja Luka. Other cities and towns include Bihać, Bosanska Krupa, Bosanski Petrovac, Čelinac, Bosansko Grahovo, Bužim, Cazin, Drvar, Gradiška, Ključ, Kostajnica, Kozarska Dubica, Kneževo, Kotor Varoš, Laktaši, Mrkonjić Grad, Novi Grad, Prijedor, Sanski Most, Šipovo, Velika Kladuša, and Prnjavor.

Operation Storm (Serbo-Croatian: Operacija Oluja / Операција Олуја) was the last major battle of the Croatian War of Independence and a major factor in the outcome of the Bosnian War. It was a decisive victory for the Croatian Army (HV), which attacked across a 630-kilometre (390 mi) front against the self-declared proto-state Republic of Serbian Krajina (RSK), and a strategic victory for the Army of the Republic of Bosnia and Herzegovina (ARBiH). The HV was supported by the Croatian special police advancing from the Velebit Mountain, and the ARBiH located in the Bihać pocket, in the Army of the Republic of Serbian Krajina's (ARSK) rear. The battle, launched to restore Croatian control of 10,400 square kilometres (4,000 square miles) of territory - representing 18.4% of the territory it claimed - and Bosniak control of Western Bosnia, was the largest land battle that took place in Europe between the end of World War II and the 2022 Russian invasion of Ukraine. Operation Storm commenced at dawn on 4 August 1995 and was declared complete on the evening of 7 August, despite significant mopping-up operations against pockets of resistance lasting until 14 August.

Operation Storm was a strategic victory in the Bosnian War, effectively ending the siege of Bihać and placing the HV, Croatian Defence Council (HVO), and the ARBiH in a position to change the military balance of power in Bosnia and Herzegovina through the subsequent Operation Mistral 2. The operation was conceived on HV and HVO advances made during Operation Summer '95, when strategic positions allowing the rapid capture of the RSK capital Knin were gained, and on the continued arming and training of the HV since the beginning of the Croatian War of Independence, when the RSK was created during the Serb Log Revolution and Yugoslav People's Army intervention. The operation itself followed an unsuccessful United Nations (UN) peacekeeping mission and diplomatic efforts to settle the conflict.
