唐朝建立之后,逐步与朝鲜半岛三国建立了宗藩关系。但高句丽在权臣盖苏文的专政下,一再破坏这种宗藩关系,攻伐新罗。于是,唐和新罗开始联合打击高句丽及百济,而学术领域有关这场战争的讨论,主要集中在对战争性质、战争原因、战争影响等方面。本文将从战争前的背景、战争的经过,战争的影响,和战争的性质这四个方面来分析这场战争。 After the founding of the Tang Dynasty, it gradually established the suzerainty relationship with the three Koreas. However, under the dictatorship of Al-Kushaven, Koguryo repeatedly destroyed such vassal relations and attacked Silla. As a result, Tang and Shilla started to jointly crack down on Koguryo and Baekje. Academic discussions on this war focused mainly on the nature of the war, the reasons for the war and the impact of the war. This article will analyze the war from the four pre-war backgrounds, the war’s passage, the impact of the war, and the nature of the war.
