Despite its political instability, Unified Silla was a prosperous country, and its metropolitan capital of Seorabeol (present-day Gyeongju) was the fourth-largest city in the world at the time. Through close ties maintained with the Tang dynasty, Buddhism and Confucianism became the principal philosophical ideologies of the elite as well as the mainstays of the period's architecture and fine arts. Its last king, Gyeongsun, ruled over the state in name only and submitted to Wang Geon of the emerging Goryeo in 935, bringing the Silla dynasty to an end.
Title: Silla
Content:  In its early days, Silla started off as a city-state by the name of Saro (Korean: 사로국, Hanja: 斯盧國), initially founded by Yemaek refugees from Gojoseon. It has also accepted dispersed people fleeing from the Lelang Commandery after Goguryeo's invasion, while later on incorporating native Jin people in the vicinity and Ye people to the North. Talhae of Silla (57–80) was the son-in-law of Namhae of Silla (4–24). According to the Samguk Sagi, Seoktalhae was the prince of Yongseongguk(龍成國) or Dapana(多婆那國), located 1,000-ri(里), northeast of Japan. Following the will of Namhae of Silla, he became the fourth king of Silla. One day, he found a low peak next to Mt. Toham(吐含山) and packed it with 
Title: Silla
Content:  Until its founding as a full-fledged kingdom, Silla was recorded using several hanja combinations to phonetically approximate its native Korean name, including 斯盧 (사로, Saro), 斯羅 (사라, Sara), 徐那(伐) (서나[벌], Seona[beol]), 徐耶(伐) (서야[벌], Seoya[beol]), 徐羅(伐) (서라[벌], Seora[beol]), and 徐伐 (서벌, Seobeol). In 504, Jijeung of Silla standardized the characters into 新羅 (신라), which in Modern Korean is pronounced "Silla". One etymological hypothesis suggests that the name Seorabeol might have been the origin of the word Seoul, meaning "capital city", and also the name of the present capital of South Korea, which was previously known as Hansung or Hanyang. The name of the Silla capital may have changed into its Late Middle Korean form Syeo-beul (셔블), meaning "royal capital city," which might have changed to Syeo-ul (셔울) soon after, and finally resulted in Seoul (서울

By the time of Beopheung of Silla (514–540), Silla was a full-fledged kingdom, with Buddhism as state religion, and its own Korean era name. Silla absorbed the Gaya confederacy during the Gaya–Silla Wars, annexing Geumgwan Gaya in 532 and conquering Daegaya in 562, thereby expanding its borders to the Nakdong River basin. Jinheung of Silla (540–576) established a strong military force. Silla helped Baekje drive Goguryeo out of the Han River (Seoul) area, and then wrested control of the entire strategic region from Baekje in 553, breaching the 120-year Baekje-Silla alliance. Also, King Jinheung established the Hwarang. The early period ended with the death of Jindeok of Silla and the demise of the "hallowed bone" (Hangul: 성골 seonggol) rank system.

The name of either Silla or its capital Seorabeol was widely used throughout Northeast Asia as the ethnonym for the people of Silla, appearing as Shiragi in Japanese and as Solgo or Solho in the language of the medieval Jurchens and their later descendants, the Manchus, respectively. In the modern Mongolian language, Korea and Koreans are still known as Солонгос (Solongos), which seems to be an alteration of Silla influenced by the Mongolian word for "rainbow" (солонго solongo). Silla was also referred to as Gyerim (鷄林, 계림), literally "chicken forest," a name that has its origins in the forest near the Silla capital. Legend has it that the state's founder was born in the same forest, hatched from the egg of a cockatrice (Korean: gyeryong, 雞龍, 계룡, literally "chicken-dragon").

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 culture of Goguryeo and Baekje where Chinese influence was more pronounced.
Title: Silla
Content:  Silla or Shilla (57 BCE – 935 CE) was a Korean kingdom located on the southern and central parts of the Korean Peninsula. Silla, along with Baekje and Goguryeo, formed the Three Kingdoms of Korea. Founded by Hyeokgeose of Silla, of the Park family, the Korean dynasty was ruled by the Gyeongju Gim (Kim) (김, 金) clan for 586 years, the Miryang Bak (Park) (박, 朴) clan for 232 years and the Wolseong Seok (석, 昔) clan for 172 years. It began as a chiefdom in the Samhan confederacies, once allied with Sui China and then Tang China, until it eventually conquered the other two kingdoms, Baekje in 660 and Goguryeo in 668. Thereafter, Later Silla occupied most of the Korean Peninsula, while the northern part re-emerged as Balhae, a successor-state of Goguryeo. After nearly 1,000 years of rule, Silla fragmented into the brief Later Three Kingdoms of Silla, Later Baekje, and Taebong, handing over power to Goryeo in 935.
Title: Silla
Content:  The final century and a half of the Silla state was one of nearly constant upheaval and civil war as the king was reduced to little more than a figurehead and powerful aristocratic families rose to actual dominance outside the capital and royal court. The tail end of this period, called the Later Three Kingdoms period, briefly saw the emergence of the kingdoms of Later Baekje and Taebong, which were really composed of military forces capitalizing on their respective region's historical background, and Silla's submission to the Goryeo dynasty.
Title: Silla
Content:  Naemul of Silla (356–402) of the Gim clan established a hereditary monarchy and took the royal title of Maripgan (麻立干; 마립간). However, in Samguk Sagi, Naemul of Silla still appears as a title of Isageum (泥師今; 이사금). He is considered by many historians as the starting point of the Gyeongju Gim (Kim) dynasty, which lasted more than 550 years. However, even when Gim monopolized the throne for more than 500 years, the worship of the founder Bak Hyeokgeose continued. In 377, Silla sent emissaries to China and established relations with Goguryeo. Facing pressure from Baekje in the west and Japan in the south, in the later part of the 4th century, Silla allied with Goguryeo. However, after King Gwanggaeto's campaign, Silla lost its status as a subordinate country. when Goguryeo began to expand its territory southward,

By the 2nd century, Silla existed as a distinct state in the southeastern area of the Korean peninsula. It expanded its influence over neighboring Jinhan chiefdoms, but through the 3rd century was probably no more than the strongest city-state in a loose federation. To the west, Baekje had centralized into a kingdom by about 250, overtaking the Mahan confederacy. To the southwest, Byeonhan was being replaced by the Gaya confederacy. In northern Korea, Goguryeo, a kingdom by about 50 CE, destroyed the last Chinese commandery in 313 and had grown into a threatening regional power.
