[1] By the 6th century AD, Gaya could not risk the hostility of either Baekje or Silla (two of the Three Kingdoms of Korea that dominated the peninsula, the third being Goguryeo).
Ara Gaya put a great deal of effort into pursuing a diplomatic solution for maintaining its independence, including hosting summits between Baekje, Silla and Yamato-Wa.
The Gaya confederacy was greatly weakened at the time, as northwestern Gaya states fell under the influence of Baekje and southeastern states fell under Silla's influence.
According to the Records of the Three Kingdoms, It is presumed the four countries, Sinunsin (臣雲遣支報),[2] Anra (安邪踧支濆), Sinbunhwal (臣離兒不例)[3] and Geumgwan (拘邪秦支廉), have superior position in southern peninsula around the 3rd century.
Archaeologically confirmed remains include Ancient Tombs in Haman Marisan.
