Buddhism during the three centuries, from the time of Seosan down to the next Japanese incursion into Korea in the late nineteenth century, remained fairly consistent with the above-described model. A number of eminent teachers appeared during the centuries after Seosan, but the Buddhism of the late Joseon, while keeping most of the common earlier characteristics, was especially marked by a revival of Hwaeom studies, and occasionally by new interpretations of methodology in Seon study. There was also a revival, during the final two centuries, of Pure Land Buddhism. Although the government maintained fairly tight control of the sangha, there was never again the extreme suppression of the early Joseon.
