Passage: 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.

How many years was Saw Mon III in eile before coming back? How many years was Saw Mon III in exile? How many years was it between Saw Mon III ame back from exile and Arakan seizing Chittagong? How many years was the region subject to Avan or Peguan interference? How many years was the weakness exposed to Avan and Peguan interference? What event happened first, Non's brother Khayi annexed or Arakan seized Chittagong? What happened first, the Forty Years War, or a unified Arakan? What happened first, the death of Razadarit, or the restoration of Arakan? What interference was the region exposed to first, Avan or Peguan? What was the title of Khayi's brother? What year was Khayi's brother exiled? Who clashed with the Arakan tribe last, the Avan or the Peguan? Who was Khayi's brother?
