明末万历二十年(1592)年,日本丰臣秀吉政权发动了侵略朝鲜的战争,对明朝主导的东亚朝贡体系公然发出挑战。关于丰臣秀吉发动这场战争的原因有多个方面,但究其主要原因,还是由日本国内政治、经济、军事方面的因素所决定。此外,朝鲜与明朝的衰落以及丰臣秀吉的个人野心也是这场战争不可忽视的因素。 Twenty years after the end of the Ming Wanli (1592), Japan’s Toyotomi Hideyoshi regime launched a war of aggression against North Korea, challenging the Ming Dynasty-led East Asian tributary system. There are many reasons for Toyotomi Hideyoshi to launch this war, but the main reason for this is still determined by the political, economic and military factors in Japan. In addition, the decline of North Korea and the Ming Dynasty and the personal ambitions of Hideyoshi Toyotomi are also factors that can not be ignored in this war.
