The tributary system of China, or Cefeng system at its height was a network of loose international relations centered around China which facilitated trade and foreign relations by acknowledging China's hegemonic role within a Sinocentric world order. It involved multiple relationships of trade, military force, diplomacy and ritual. The other states had to send a tributary envoy to China on schedule, who would kowtow to the Chinese emperor as a form of tribute, and acknowledge his superiority and precedence. The other countries followed China's formal ritual in order to keep the peace with the more powerful neighbor and be eligible for diplomatic or military help under certain conditions. Political actors within the tributary system were largely autonomous and in almost all cases virtually independent.

Joseon, officially Great Joseon State, was a dynastic kingdom of Korea that lasted just over 500 years. It was founded by Taejo of Joseon in July 1392 and replaced by the Korean Empire in October 1897. The kingdom was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amnok and Tuman through the subjugation of the Jurchens.
