   The immediate result of the war was the collapse of the Pagan Empire . However , the war merely accelerated the collapse but did not cause it . Pagan 's disintegration was " in fact more prolonged and agonized . " The kingdom had been in long gradual decline since the early 13th century . Had Pagan possessed a stronger central government , the collapse could have been temporary , and the country “ could have risen again ” . But the dynasty could not recover , and because the Mongols refused to fill the power vacuum , no viable center emerged in the immediate aftermath . As a result , several minor states fought it out for supremacy for the better part of the 14th century . It was only in the late 14th century that two relatively strong powers emerged in the Irrawaddy basin , restoring some semblance of normalcy . The vast region surrounding the Irrawaddy valley would continue to be made up of several small Tai @-@ Shan states well into the 16th century .   = = = Rise of Tai @-@ Shan states = = =   Perhaps the most enduring legacy of the Mongol invasions was the emergence of Tai @-@ Shan states in mainland Southeast Asia . The Tai @-@ Shan people who came down with the Mongol invasions stayed . By the early 14th century , several Tai @-@ Shan states had come to dominate a vast region from present @-@ day Assam to northern and eastern Myanmar to northern and central Thailand and Laos . Their rise was encouraged by the Mongols , who viewed the states as a useful buffer between Yunnan and the rest of Southeast Asia . The Mongols , who were still trying to incorporate Yunnan into the central administration , were unwilling or unable to make necessary sustained investments to bring the vast regions south of Yunnan into the fold . ( The integration of Yunnan itself into “ China Proper ” was to take several more centuries , and continues to today . ) As such , from the newly formed Tai @-@ Shan states in western and central Southeast Asia to Dai Viet and Champa in eastern Southeast Asia , the Mongols elected to receive nominal tribute . Though the rulers of these states were technically governors of the Yuan government , they were the native chieftains , “ who would have ruled there in any case , and they did as they pleased . ”   = = = Arrival of China on the Burmese border = = =   The war also marked the arrival of China at the doorstep of Burma . The old Dali Kingdom , known to the Burmese as Gandalarit ( ဂန ္ တလရာဇ ် , after Gandhara Raj ) was now a Mongol Chinese province . ( The Burmese now called the new powers at Yunnan " Taruk " after the Turkic @-@ speaking soldiers of Yunnan . Over the years , the term Taruk came to be used to refer to the Han Chinese . Today , King Narathihapate is remembered as Taruk @-@ Pye Min , ( " the King who fled from the Taruk [ Chinese ] ) . ) From a geopolitical standpoint , the Mongol – Chinese presence in Yunnan pushed the Shan migrations in the direction of Burma ( and parts of the Khmer Empire ) . The raids by various Shan states into Upper Burma would continue until the mid @-@ 16th century .   = = Mongolia – Myanmar relations = =   During the official visit by the President Tsakhiagiin Elbegdorj to Myanmar in November 2013 , Aung San Suu Kyi , the chairperson of National League for Democracy , said this was the first ever Mongol mission since the Mongols came 730 years earlier .   = Battle of Edson 's Ridge =   The Battle of Edson 's Ridge , also known as the Battle of the Bloody Ridge , Battle of Raiders Ridge , and Battle of the Ridge , was a land battle of the Pacific campaign of World War II between Imperial Japanese Army and Allied ( mainly United States Marine Corps ) ground forces . It took place from 12 – 14 September 1942 , on Guadalcanal in the Solomon Islands , and was the second of three separate major Japanese ground offensives during the Guadalcanal Campaign .   In the battle , U.S. Marines , under the overall command of U.S. Major General Alexander Vandegrift , repulsed an attack by the Japanese 35th Infantry Brigade , under the command of Japanese Major General Kiyotake Kawaguchi . The Marines were defending the Lunga perimeter that guarded Henderson Field on Guadalcanal , which was captured from the Japanese by the Allies in landings on Guadalcanal on 7 August 1942 . Kawaguchi 's unit was sent to Guadalcanal in response to the Allied landings with the mission of recapturing the airfield and driving the Allied forces from the island .
