乐浪郡
In the 1st century AD, the Wolji/Mokji (月支/目支) state, that formed and led Mahan confederacy, was defeated in struggles with Baekje, another member of Mahan, and consequently losing whole region of present-day Han River basin. But the San Guo Zhi recorded the Han state fallen in struggles with the Lelang Commandery and Daifang Commandery in the 246. Under continuous pressure from Baekje, only 20 statelets of Mahan confederacy survived until the late 3rd century. Baekje eventually absorbed or conquered all of Mahan by the 5th century, growing into one of the Three Kingdoms of Korea, along with Silla and Goguryeo.
