The term "Injo" refers to the 16th king of the Joseon Dynasty in Korea, reigning from 1623 to 1649. His rule is marked by political instability and conflict, particularly due to the power struggles between different factions within the court. Injo's reign began after a coup that ousted his predecessor, leading to a turbulent period in Korean history. Injo faced significant challenges, including invasions by the Manchu people, which ultimately led to the downfall of the Joseon Dynasty. His inability to effectively respond to these threats contributed to the dynasty's decline, and his reign is often viewed as a time of crisis for Korea.
