Goryeo's Century of Golden Age and Tripitaka Koreana

The 12th century (1100s) is recognized as a period of cultural development and economic activity in the Goryeo Dynasty, following the relative stability achieved after the Goryeo–Khitan Wars of the 11th century. With fewer large-scale external conflicts, the kingdom experienced conditions that supported advancements in trade, the arts, and education across the Korean Peninsula. During this time, the capital city of Gaegyeong (modern-day Kaesong) developed into an active center of international trade. Historical records indicate that merchants from Song China and regions as far as the Islamic world engaged in commerce with Goryeo. Goods such as silk, spices, and ivory were exchanged for locally produced items including ginseng and high-quality paper. This level of trade reflects the kingdom’s integration into broader regional and intercontinental networks. The 12th century is also noted for developments in ceramic production, particularly Goryeo celadon (cheongja). Craftsmen refined techniques to produce pottery with a distinctive jade-green glaze and detailed inlay designs known as sanggam. Surviving examples from this period are preserved in museums and collections, demonstrating the technical skill and aesthetic standards achieved during this era. In addition to economic and artistic activity, the Goryeo state supported formal education. The Gukjagam, the national academy, along with various private institutions, trained members of the elite in Confucian texts and administrative practices. This contributed to the development of a structured bureaucratic system and a literate governing class. These developments took place alongside the continued influence of Buddhism, which remained an important aspect of religious and cultural life in Goryeo society throughout the century.
