One incident of a peculiarly Korean character deserves mention. Some money was stolen from the strong room of a fortress near Song-do. The store-house keeper was suspected but there was no evidence. So the commandant secretly questioned the keeper’s little son and found that the suspicion was correct. The keeper was punished but the commandant was also cashiered from the fact that he had induced a boy to incriminate his own father. The native records say that in the twelfth year of this sovereign, in 1686, Roman Catholicism entered Korea for the first time. Certain foreigners entered the country and preached the new doctrine. We are not told of what nationality these men were but it was long before any European attempted to enter Korea. We are told that the new doctrine spread rapidly and that some of the highest officials asked the king to send the foreigners out of the country. Whether this was done cannot now be learned. Nothing is said of this in the French work on the Roman Catholic Mission in Korea, and it is somewhat difficult to understand. It would hardly be found in the records, however, were there not some ground for the statement. * * * * * The following year beheld events that were to result in another violent revolution and in the driving from the seat of power the No-ron party and the reinstatement of the Nam-in. It all grew from the king’s taking a concubine, Chang, who soon gained complete ascendency over him. A rumor arose that the queen was to be deposed and when Han Söng-u expostulated with the king, the latter flew into a passion and drove him away. The following year the concubine presented the king with a son, the most unfortunate thing that could have happened, for, the queen being as yet childless, it served to put the king more entirely under the influence of the concubine. Trouble followed immediately. The king said “I am now forty years old and have no son by the queen. The people are getting uneasy. As I have gotten a son by a concubine I intend to make him Crown Prince, and anyone may object at his peril.” In this way he threw as it were a torch into a powder magazine. The No-ron party who were in power, were in arms at once for they knew that the opposition had been using the concubine to undermine their influence. Memorials poured in from all sides reminding the king that he was still young, that there was no need of haste in appointing the queen a successor. These memorials the king answered by banishing the senders. Even Song Si-ryŭl who had entered a mild protest, was stripped of rank and sent outside the city. The Nam-in party then stepped once more into power. From the Prime Minister down all offices were again turned over to them. Song Si-ryŭl was banished to Quelpart, but the Nam-in were not content with that, and demanded his death. So he was summoned back to Seoul. Posthumous honors were given to many of the Nam-ins whom the king had
