This episode we go back to the continent for a bit to see how things are going. Hint: not well. While Yamato was building its new bureaucratic state, Goguryeo, Baekje, and Silla were battling it out while the Tang empire and their ambitions loomed over them all. Yamato is about to get pulled into the conflicts, but before that, let's look at what was happening from the point of view of the various penninsular polities.

This episode goes back over some of the information in Episodes 107 and 109, but mainly to place it in context of what was happening in Goguryeo, Baekje and Silla as opposed to simply viewing it from the rise of the Tang Empire or the occasional mentions in the Nihon Shoki. Much of it relies on what we have in the Samguk Sagi, the Korean annals of the Three Kingdoms.

Rough Transcript

Welcome to Sengoku Daimyo’s Chronicles of Japan. My name is Joshua and this is Episode 115: Red Banquets, Fashion Disasters, and Other Continental Adventures

It was the year 642, and the hall was decked out in the finest, with banners hung and tables set. The scene was awash in gold and silk and silver. The guests were no less opulently adorned: The crème de la crème of Burana, aka Pyongyang, capital of the state of Goguryeo. The tables were piled high with food, and there was a low murmur as the assembled guests talked quietly as they waited for their host. These guests were among the highest nobles in the land. 180 members of the most powerful families. As they mingled, they talked. Much of it was gossip, the currency of court politicians everywhere. They discussed who was up and down in the constant fight for favor. Who had made a misstep, or was seen talking to the wrong person? Or how about that time that someone wore the wrong clothes, or misspoke in court? Other conversations focused outward, on the threats from beyond the border. But the majority of conversation had to do with their host, a striking individual. The murmurs continued as they waited for him to arrive.. Yeon Gaesomun was a hard-liner, pushing his agenda for stronger defenses against Tang encroachment. That might be understandable for someone stationed out east, as he had been, but the King himself and his supporters felt that relations needed a more diplomatic touch. Now that Gaesomun was back in the capital of Pyongyang, would he change his approach? The conversation continued apace as people ate and drank. The whole time they remained blissfully unaware of what was happening just outside. Drowned out by the sound of the banquet, troops were quietly assembling just outside, girding themselves for what would soon be an irrevocable step forward. As orders came down the line, they drew their weapons, and then they burst through the doors…

Last episode we talked through much of the Hakuchi era, from 650 to 654. This episode I want to finish out the era, in order to do so we’re once again going to touch on what was happening over on the continent. Some of these events we’ve talked about already: Last time we did a deep dive into this subject, back in Episode 104, we focused primarily on the Tang dynasty and its rise. We also talked somewhat about Yamato’s conflicts with Tang, Goguryeo, and others in Episode 107. But at this point it’s useful to go back and put that Continental narrative together a little bit more clearly, to set the stage for what will be happening in Yamato in the next reign after Karu. This episode we are going to go back over some of that info, but I want to center the narrative a bit more on the peninsula, rather than on the Tang dynasty. As you may recall, the Tang dynasty started in approximately 618, taking over from the Sui. By 628, the Tang had defeated the Gökturks, and they continued to expand. They conquered Turpan and Gaochang, in the Western Regions, and their control over the Silk Road was substantial, opening up tremendous trade routes that brought in wealth and more. The capital of Chang’an became a true center of learning, and the government instituted a national university that was attended by elites from both in and outside the empire. This episode, though, we are going to focus more on the area of the Korean and Liaodong peninsulas, where the countries of Goguryeo, Baekje, and Silla contended with each other. Goguryeo was the largest and perhaps even the most powerful of the three, but it was also on the border with the Tang empire, who were nothing to sneeze at given their own string of military victories. So Goguryeo was beset from all sides, and needed a sizeable force on their western border. Everything was in a tenuous balance, of sorts. When it came to the Tang empire, Goguryeo walked a delicate line. On the one hand, they wanted access to the trade goods and the knowledge that was accumulating in the Tang empire and making it the envy of most other nations in the region. On the other hand, they had to be constantly on the lookout for a possible invasion, and so needed to show their strength. This wasn’t without some confidence. After all, Goguryeo had defeated attempts by the Sui dynasty to invade, and so they had proved up to the challenge—at least so far. In 619, on the eve of the Tang dynasty’s founding, King Yeongnyu of Goguryeo, whose personal name was Geonmu, sent a tribute mission to the Tang, to encourage good relations. By 622, Goguryeo was responding to the Tang dynasty’s request to return soldiers captured during the attempted invasions by the Sui. They kept sending missions on an annual basis, playing the part of a friendly tributary. Further on the peninsula, Baekje and Silla were likewise reaching out to the Tang dynasty, similarly hungry for the trade goods available in the markets of Chang’an. Baekje, sitting on the coast of the Bohai sea, had direct routes to the mainland; to both the Yellow river and Yangzi river deltas. They may not have had an overland border, but the sea was open to them. Silla, on the other hand, was not so quite so fortunate. They were mainly situated on the east side of the peninsula, and though they had some access through the Han river, near modern Seoul, their access was constantly threatened by both Baekje and Goguryeo. In 626, a Silla mission to the Tang complained about this very thing, claiming that Goguryeo was attacking them. In response, the Tang requested peace, and Goguryeo apologized and backed down. That said, it is unclear if the Tang would have taken much action. They were, at that point, more focused on the Gökturks and others. That military action ended with the defeat of the Gökturks in 628, however, a victory for which Goguryeo sent congratulations. One has to imagine, however, that the congratulations were a bit mixed. After all, without the Gökturks to hold their attention, what was to keep the Tang dynasty from looking at further conquest? The question of how to react to the Tang Empire seems to be one that split the Goguryeo court. Some members of the court wanted to appease the giant on their doorstep, with offers of tribute and nominal submission, with the goal of making it clear that they were not a threat and that military conquest was unnecessary. They could all live in harmony, one with the other. To that end, they would not want to be too blatant about building up their forces or defenses in an act that could be seen as a prelude to military action. On the other side were the hard-liners: members of the court that felt that they had to maintain a strong military defense against the likely possibility of a Tang offensive. To these hawks, military strength was the deterrent, as power only truly respected power. To be seen as weak and submissive would be to seem vulnerable, and an easy target. Still, there seems to have been relative, if uneasy, peace for a time. Goguryeo continued to build their relation as a tributary state, and most of the action seems to have actually been taking place in the peninsula. For Silla, 632 was a banner year, as Queen Seondeok came to the throne. She was the eldest daughter of her father, who had no sons to inherit, and so she came to the throne. She is said to have been quite intelligent, and the Samguk Sagi gives various accounts of her Holmsian powers of deduction. For example, upon seeing a picture of flowers, she immediately concluded that, though they were beautiful, they had no fragrance. She noted the lack of bees and butterflies around the flowers, and based on that observation she deduced that the flowers must have no scent to attract them. Queen Seondeok would oversee Silla in a time when they were growing closer to the Tang and also seeing increased pressure from Baekje and Goguryeo. We mentioned how, in 626, Goguryeo had blocked Silla’s mission to the Tang court. Then, in 636, a Baekje general led 500 troops to Mt. Doksan, to attack the Silla position there. Two years later, Silla defeated Goguryeo troops outside Jiljung Fortress. This wasn’t constant warfare, but it did mean that the armies had to be on a constant wartime footing. You never knew when your neighbor might sense a moment of weakness and try to take advantage of it. Of course, as the old adage goes, “the enemy of my enemy is my friend”. Baekje and Goguryeo were more directly on the Tang Empire’s borders. And so we see Silla cultivating a special relationship with the Tang. This is nothing new, by the way. Various dynasties in the Yellow River basin had used similar tactics for generations. Immediate border countries were often treated more severely, with threats of punitive expeditions if they did not fall in line or give themselves over completely to become a direct vassal of the empire. Countries just beyond the border were often treated with a lighter touch, luring them into complacency and even friendship with access to elite tra...
