In 1371 Sin-don, the court favorite by deceit, is exposed and killed. Over against this victory is the negative fact that the King is given over to sodomy and Japanese pirates invade Seoul, and burn it down.

1374. The King is assassinated. His supposed son, from Sindon, ascends. But the Chinese Ming dynasty draws the line at any acceptance of Koryo: they point out that an assassination and a questionably legitimate heir are reasons for them to hesitate at the validity of any alliance.

In 1378 rising star Yi Tajo is put in charge of all the military. His is the one strong life in a nation gone weak from the top down. Through his influence the occasional raids of the Japanese are quelled.

The new King can't decide whether to favor the Ming dynasty or the old Mongolian power, descending as is Koryo into history. He is double-minded about this for some time, and additionally, he continues in many of his father's evil ways. The drinking, the women, the hunting, the stealing. Koryo has lost its moral compass.

The Japanese come on worse than ever as they see such weakness. But Tajo wins yet another victory. Slowly the people begin to expect him to deliver them. That seems to be his own growing awareness too.

In 1383, the Capital is moved back to Seoul, then to Kaesong, currently a part of North Korea, in between Seoul and Pyongyang.

By 1386, the Ming have decided to recognize the King of Koryo. But, in 1388 the King decides to attack Liao-tung, in Ming territory. Yi Tago warns against it, believing it will destroy Koryo. The man caught up in his flesh will always make wrong decisions. We cannot call Yi Tajo a spiritual man by any means, but he seems to be directed by higher standards, and to that extent he raises expectations in Korea.

As plans begin to march to the northern regions against Ming, the Japanese are allowed to enter the south unopposed. Yi and his army are forced to turn around and march on Kaesong to stop Gen. Choe, the master of the plan. Some see this as Tajo's "Crossing of the Rubicon" , or in his case, the Yalu.

The weak-kneed King turns Choe over to Yi Tajo, who banishes him with a "Go in peace." Then the King is likewise banished. His adopted son is placed on the throne, while Tajo waits for the right moment. The new "king" is not of royal blood. He is often not listed as a King of Koryo. Yet Tajo is hesitant.

In 1389, the Capital comes back to Seoul again. But the King decides to remain in Kaesong amidst the almost universal wish that Yi Tajo be king. Tajo's relatives murder and banish all of his opposition to push him throne-ward. Finally, in 1392 the King abdicates and turns over the kingdom to Yi-Tajo. 475 years of Koryo rule have come to an end.

The Yi dynasty will prove to be a lasting one. In fact, the last one. Not until the aggression of Japan annexes Korea in 1910 will the Yi Dynasty be forced out of power. It is this period of time that shapes and molds Korea into its pre-modern form. Much of Yi remains to this day.

And it will be during the Yi "Chosun" period that Jesus Christ and His claims are offered to the people of this ancient and proud land. Their response is amazing. How the Koreans have loved Jesus! That makes all the worse the rule of the present tyrant of the North, who keeps the people from their appointed fellowship with God through Christ.
