For the release of the new Sucker Punch video game, Ghost of Tsushima, which depicts a lone samurai defending a Japanese island from Mongol invaders, we’re going to change up our presentation for a few episodes.  This will be the first in a three part series looking at the Mongol invasions of Japan, a slight jump ahead in the timeline of our episodes so far, going from the reign of Great Khan Mongke to that of his younger brother, Kublai Khan. This first episode will provide greater context to the game, discussing the cause of the first Mongol invasion of Japan in 1274, the actual battle for Tsushima island and the fighting in Hakata Bay.  Our following episode will detail the story of Takezaki Suenaga, a samurai who fought against both invasions and later produced a brilliant set of scrolls depicting his exploits. The final episode will cover the oft-overlooked consequences of the invasion on both Japan and Kublai Khan’s empire, as well as its historical legacy: altogether, we hope to provide an accurate and well rounded view of the historical events surrounding the game utilizing both primary sources and scholarly literature. I’m your host David, and this is Kings and Generals: Ages of Conquest.       Japan first came to Mongol attention through Japanese raids against the Korean peninsula. Called wakō, piracy against the Korean coastline had existed for centuries, but picked up again in the 1220s during Korean weakness caused by the Khitan and Mongol invasions, covered in our previous episodes. The island of Tsushima, situated between Korea and Japan, was a prominent base for these pirates making the short trip over the straits to strike undefended settlements. These attacks were not court sanctioned, a crime of individual opportunity rather an organized effort. By the time the Korean leadership finally submitted in 1259 the raids had largely ceased, but it meant the existence of Japan was known to the Mongols. The new King of Korea in 1260, King Wonjong, had a good relationship with the new Mongol Emperor, Kublai. We will return to Mongke’s reign after these episodes, but for those of you who do not know, Mongke Khan died on campaign in China in August 1259. Two of his younger brothers, Kublai and Ariq Boke, both declared themselves Khaan in the months following. Known as the Toluid Civil War, Kublai based in China was able to overcome his brother based in Mongolia by 1264. Consequences were immense: Mongol imperial unity was shattered as the Mongol ruled Khanates across western Asia began their own conflicts, the Hulegu-Berke war between the Ilkhanate and Golden Horde. Kublai had defeated Ariq, but lost the empire. His authority beyond the western borders of China was only nominal, and the Khanates were effectively independent states from that point on, though contact remained between them. Kublai, by necessity, was forced to focus his continued conquests on China and the surrounding territories.      Kublai’s main target was the Song Dynasty, which ruled southern China. A huge economic power with a massive population, the Song war was a difficult task. The Mongols needed to resort to indirect strategies to help bypass the frontier: in the 1250s, Kublai had conquered the Kingdom of Dali, in China’s modern Yunnan province, to open a front on the southwest of the Song. The Japanese, who had trade ties with the Song, were another direction Kublai could exert his influence. Forcing the Japanese to cut trade with the Song would help weaken the Song economy, and so aid Kublai’s overall war with them. Further, like his brother Mongke, Kublai firmly believed in the eventuality that all of the world was to come under Mongol rule. Bringing in the submission of the Japanese was merely Kublai enacting heaven’s will. He had one other concern that his predecessors did not. Despite controlling Mongolia, the core of Kublai’s realm was China, and tied himself to Chinese imperial tradition for legitimacy there. In classic Chinese tradition
