the Phoenicia of East Asia, was instrumental in the dissemination of Buddhism throughout East Asia and continental culture to Japan. Baekje played a fundamental role in transmitting cultural and material developments to ancient Japan, including Chinese written characters, Chinese and Korean literature, technologies such as ferrous metallurgy and ceramics, architectural styles, sericulture and Buddhism. Baekje exerted its political influence on Tamna, a kingdom that ruled Jejudo. Baekje maintained a close relationship with and extracted tribute from Tamna. Baekje's religious and artistic culture influenced Goguryeo and Silla. Baekje was once a great military power on the Korean Peninsula, especially during the time of Geunchogo, but was critically defeated by Gwanggaeto and declined. In the late 5th century, under attack from Goguryeo, the capital of Baekje was moved south to Ungjin (present-day Gongju) and later further south to Sabi (present-day Buyeo). Baekje was conquered by Silla-Tang alliance in 660, submitting the Unified Silla. Silla According to Korean records, in 57 BC, Seorabeol (or Saro, later Silla) in the southeast of the peninsula unified and expanded the confederation of city-states known as Jinhan. Although Samguk Sagi records that Silla was the earliest-founded of the three kingdoms, other written and archaeological records indicate that Silla was likely the last of the three to establish a centralized government. Silla was the smallest and weakest of the Three Kingdoms of Korea, but it used cunning diplomatic means to make opportunistic pacts and alliances with the more powerful Korean kingdoms, and eventually Tang China, to its great advantage. Renamed from Saro to Silla in 503, the kingdom annexed the Gaya confederacy (which in turn had absorbed Byeonhan earlier) in the first half of the 6th century. Goguryeo and Baekje responded by forming an alliance. To cope with invasions from Goguryeo and Baekje, Silla deepened its relations with the Tang dynasty, with her newly gained access to the Yellow Sea making direct contact with the Tang possible. After the conquest of Goguryeo and Baekje with her Tang allies, the Silla kingdom drove the Tang forces out of the peninsula and occupied the lands south of Pyongyang. The capital of Silla was Seorabeol (now Gyeongju; "Seorabeol", "서라벌", is hypothesized to have been the ancient Korean term for "capital"). Buddhism became the official religion in 528. The remaining material culture from the kingdom of Silla including unique gold metalwork shows influence from the northern nomadic steppes, differentiating it from the
