Problem: During the continuous skirmishing of the 1260s, both sides employed Muslim soldiers, mostly Turcopoles, against their Christian foes. In 1266, the Genoese had made an alliance with Baibars, who was to outfit some troops for an expedition against Acre, but the Genoese' promised fleet never got underway. In 1267, Genoa managed to capture the Tower of Flies and blockade the harbour of Acre for twelve days before being evicted by a Venetian flotilla. The ongoing warfare between Genoa and Venice had a major negative impact on the Kingdom's ability to withstand external threats to its existence. Save for the religious buildings, most of the fortified and defended edifices in Acre had been destroyed at one point or other and according to Rothelin, the continuator of William of Tyre's History, 20,000 men in total had lost their lives, a frightful number considering the Crusader states were chronically short on soldiery. The War of Saint Sabas was settled in 1270 with a pact to cease the hostilities between the Venetians and the Genoese. In 1288, Genoa finally received their quarter in Acre back.

Problem: Another key development in the wake of the Forty Years' War was the emergence of a unified and powerful Arakan. The western littoral between the Arakan Yoma and the Bay of Bengal remained politically fragmented even after Pagan's fall. The coast was divided between at least two power centres at Launggyet in the north and Sandoway in the south. The weakness became exposed between 1373 and 1429 when the region was first subject first to Avan and then to Peguan interference. Arakan was Pegu's vassal from 1412 at least until Razadarit's death in 1421. The restoration came in 1429 when the last king of Arakan, Saw Mon III, in exile since 1406, came back with an army provided by Sultan Jalaluddin Muhammad Shah of Bengal. Narameikhla again became king, though as a vassal of Bengal. The vassalage was brief. In 1437, Saw Mon's brother Khayi annexed Sandoway and Ramu, his overlord's territory, unifying the Arakan littoral for the first time in history. An ascendant Arakan seized Chittagong in 1459, and received tribute from the Ganges delta.

Problem: During the Democratic Kampuchea days, the 68,000-member Khmer Rouge-dominated CPNLAF force, which completed its conquest of Phnom Penh, Cambodia in April 1975, was renamed the RAK . This name dated back to the peasant uprising that broke out in the Samlot district of Battambang Province in 1967. Under its long-time commander and then Minister of Defense Son Sen, the RAK had 230 battalions in 35 to 40 regiments and in 12 to 14 brigades. The command structure in units was based on three-person committees in which the political commissar ranked higher than the military commander and his deputy. Cambodia was divided into zones and special sectors by the RAK, the boundaries of which changed slightly over the years. Within these areas, the RAK's first task was the peremptory execution of former Khmer National Armed Forces officers and of their families, without trial or fanfare to eliminate KR enemies. The RAK's next priority was to consolidate into a national army the separate forces that were operating more or less autonomously in the various zones. The Khmer Rouge units were commanded by zonal secretaries who were simultaneously party and military officers, some of whom were said to have manifested "warlord characteristics". Troops from one zone frequently were sent to another zone to enforce discipline. These efforts to discipline zonal secretaries and their dissident or ideologically impure cadres gave rise to the purges that were to decimate RAK ranks, to undermine the morale of the victorious army, and to generate the seeds of rebellion. In this way, the KR used the RAK to sustain and fuel its violent campaign.
