Joseon Dynasty Historical Timeline

So…I have lots of unpublished drafts containing a lot of timelines related to the era of different Joseon kings, hence this thought: why don’t I just put the timelines together as a mega timeline of Joseon’s major events? This list is non-exhaustive, but I’m trying to include major events like birth and death of Joseon kings and queens, birth and death of notable royal princes and princesses, wars, published documents and books, and various happenings that affected Joseon as a whole. Keep the suggestions coming if you have any, because two brains are better than one! I might have missed some details so don’t hesitate to leave any additional information and correction 😉

1389 November: King Chang dethroned and replaced with King Gongyang.
1391 The Rank Land Law/ Gwajeonbeop 과전법 科田法 was institutionalized, based on Jo Joon’s land reform proposal as a new way to manage land tax by awarding the right to collect land taxes to government officials according to their ranks.

Dissatisfied with Taejo’s intention to honour Queen Sindeok as a formal consort, the princes raised their private armies the Crown Prince deposed and banished before being assassinated shortly afterwards. The Crown Prince’s seat went to the second son of Taejo, Yi Bang-gwa (Prince Yeongan), since the eldest son Yi Bang-woo (Prince Jinan) already passed away in 1393.
