Final answer:
The Yi dynasty, known as the Joseon dynasty, maintained control over Korea by establishing vassalage to the Ming dynasty, reinforcing a centralized Confucian government structure, and adapting Chinese civil service elements while maintaining aristocratic power.
Step-by-step explanation:
The Yi dynasty, also known as the Joseon dynasty, was able to maintain control over Korea for five centuries through various measures. One significant strategy was establishing friendly relations and acknowledging the suzerainty of the more powerful Ming dynasty, thus securing protection and trade benefits. Yi Seong-gye, the founder of the Joseon dynasty, capitalized on this relationship after taking control by respecting the status quo and saving Korea from potential conflict with a powerful neighbor.
Furthermore, inside Korea, the Joseon dynasty maintained a centralized government and reinforced Confucian social structures. This societal model upheld hereditary rank and supported a strong, stable ruling class. By promoting Confucian ideals, the dynasty could effectively manage land and labor, thereby cementing their authority and control over the Korean people.
The dynasty also adapted elements of the Chinese examination system to bolster bureaucratic merit while ensuring that high aristocrats retained significant influence over local governance. These aristocrats managed entire villages and appointed local officials, thereby controlling the populace and reinforcing the dynasty's power structure.
