Richard arrived at Acre on 8 June 1191 and immediately began supervising the construction of siege weapons to assault the city, which was captured on 12 July. Richard, Philip, and Leopold quarrelled over the spoils of the victory. Richard cast down the German standard from the city, slighting Leopold. In the struggle for the kingship of Jerusalem, Richard supported Guy, while Philip and Leopold supported Conrad, who was related to them both. It was decided that Guy would continue to rule but that Conrad would receive the crown upon his death. Frustrated with Richard , Philip and Leopold took their armies and left the Holy Land in August. Philip left 7,000 French crusaders and 5,000 silver marks to pay them. On 18 June 1191, soon after Richard's arrival at Acre, he sent a messenger to Saladin requesting a face to face meeting. Saladin refused, saying that it was customary for kings to meet each other only after a peace treaty had been agreed, and thereafter "it is not seemly for them to make war upon each other". The two therefore never met, although they did exchange gifts and Richard had a number of meetings with Al-Adil, Saladin's brother. Saladin tried to negotiate with Richard for the release of the captured Muslim soldier garrison, which included their women and children. On 20 August, however, Richard thought Saladin had delayed too much and had 2,700 of the Muslim prisoners decapitated in full view of Saladin's army, which tried unsuccessfully to rescue them. Saladin responded by killing all of the Christian prisoners he had captured.

The Russo-Circassian War involved a series of battles and wars in Circassia, the northwestern part of the Caucasus, in the course of the Russian Empire's conquest of the Caucasus. Fighting lasted approximately 101 years, starting in the reign of Empress Catherine the Great and finishing in 1864. Although the Russian conquest of the Caucasus started at least as early as the Russo-Persian Wars, the term Caucasian War commonly refers only to the period 1817-1864. Those who use the term Russian-Circassian War take its starting date as 1763, when the Russians began establishing forts, including at Mozdok, to be used as springboards for conquest. The Caucasian War ended with the signing of loyalty oaths by Circassian leaders on 2 June1864. Afterwards, the Ottoman Empire offered to harbour the Circassians who did not wish to accept the rule of a Christian monarch, and many emigrated to Anatolia, the heart of the Ottoman territory and ended up in modern Turkey, Syria, Jordan, Israel, Iraq and Kosovo. Different smaller numbers ended up in neighbouring Persia. Various Russian, Caucasus, and Western historians agree on the figure of ca. 500,000 inhabitants of the highland Caucasus being deported by Russia in the 1860s. A large fraction of them died in transit from disease. Some of those that remained loyal to Russia were settled into the lowlands, the left-bank of the Kuban River.

The desire for a permanent connection across the Limfjord at Aggersund dates back to the early 1900s. In the mid-1920s, citizens in Lgstr reduced a selection, which appeared with a number of suggestions for a bridge. However, the initiative stranded controversy about the alignment and funding. In 1936, the idea was resumed by the Ministry of Employment and Social Affairs and the Ministry of Transport as a possible employment measure, and in 1939 the construction of the bridge, which was funded by Aalborg, Hjrring and Thisted Amter, began. The bridge was projected by Christen Ostenfeld. The initiation took place on 18 June 1942. The bridge cost about 3.5 million DKK. During the German occupation of Denmark, the bridge was strategically important for the German shipments of crew and equipment to and from Norway. Therefore, a military support point was built in 1943-44, consisting of 11 concrete plants on the north side and 6 on the south side. In addition, minefields and other types of barriers were introduced. Two large Flak bunkers on the south side and one on the north side are still available and are available. The other smaller bunkers have either been removed or located in a private area without public access. In 2000, the Aggersund Bridge beams were strengthened, increasing the carrying capacity of the bridge. Coordinates: 565958N 91738E / 56.9995N 9.2940E / 56.9995; 9.2940
