Final answer:
Korean arts and literature flourished during the time of relative isolation in the Joseon dynasty, with significant cultural and scholarly developments, emphasizing Confucian ideals.
Step-by-step explanation:
Korean arts and literature indeed experienced a period of flourishing during the Joseon dynasty, which reigned during Korea's time of relative isolation from the late 16th to the late 19th century. Despite internal strife and invasions, Korea during the Joseon dynasty emphasized scholarly Confucian ideals and pursued cultural developments, which included the creation of the Korean alphabet, Hangul, and advancements in Confucian literature and philosophy. The Silhak movement, advocating for practical science and technology solutions to social issues, also marked this era. This period of self-imposed isolation allowed Korea to consolidate its own cultural identity, distinct from its neighbors, while maintaining limited relations with China and Japan.
