Changes and Background in the long spear of the Early Iron Age~Three Kingdoms Period

In the ancient East Asian War, long spear were frequently used. In this study, long spear excavated from the Korean Peninsula from the early Iron Age to the Three Kingdoms period were analyzed and their transformation was examined. Long spear appear for the first time on the Korean Peninsula during the early Iron Age. Long spear equipped with copper weapons combined with wooden rods may have first appeared on the Korean Peninsula in the 5th and 4th centuries BC during the spread of Chinese bronze weapon culture. In the Proto-Three Kingdoms Period, the material of Long spear turns into iron, and iron ferrule appears. As a background, it is desirable to consider the spread of Han(漢) culture through Nakrang. In the Three Kingdoms Period, the types of Long spear become diverse. Long spear related to Ancient Japan(倭) appear mainly in Gim-hae and Bu-san, and long spear ranging from 400 to 500 centimeters also appear in the 5th century. In addition, decorative Long spear that are not aimed at killing are also produced, and new combinations such as iron barbed implement(有刺利器)-iron ferrule are also confirmed. Since the 6th century, the number of Long spear whose length can be known has dropped sharply, which is related to changes in burial customs such as burial and cremation. However, considering war-related articles, including excavations from the Unified Silla Dynasty, it can be seen that Long spear were continuously used in the Korean Peninsula war even after the 6th century.
