Changes in Storage Patterns during the Formation of the Baekje State

In the process of state formation, storage methods can change according to political, economic, and social transformations. This study aims to identify such changes in storage methods, storage amounts, and stored crops by comparing and analyzing various types of archaeological evidence, such as crop remains, pottery, storage pits, and above-ground structures from sites of the central region of the Korean Peninsula dating the Proto-Three Kingdoms to Baekje’s Hanseong period. The results of the analysis revealed that, in the Gyeonggi region, the tendency to store crops indoors was weakened by the Hanseong period. However, in major settlements, this tendency persisted, and the use of external storage facilities increased, with rice becom-ing a significant crop for external storage. In the Yeongseo region, the change in indoor storage methods was not as distinct as in the Gyeonggi region, but there was a noticeable change in external storage patterns. Overall, the use of deep storage pits increased, new storage crops were added, and the use of external storage facilities increased somewhat in the Namhan River basin. Analyzing the reasons for these changes based on contemporary contexts, it was found that both the Gyeonggi and Yeongseo regions were influenced by changes in agricultural production methods. In the case of the Gyeonggi region, the in-creased complexity of society, such as the intensification of social stratification and the dif-ferentiation of site functions, also influenced storage strategies.
