Two Japanese invasions of Korea and subsequent battles on the Korean peninsula take place during the years 1592-1598.

Toyotomi Hideyoshi leads the newly unified Japan into the first invasion (1592-1593) with the professed goal of conquering Korea, the Jurchens, Ming Dynasty China, and India.

The second invasion (1594-1596) has no lofty goal of world conquest and is aimed rather solely as a retaliatory offensive against the Koreans.

The invasions are also known as Hideyoshi's invasions of Korea, the Seven Year War (in reference to its span) and the Imjin War (in reference to the "Imjin" year of the sexagenary cycle in Korean).

The Japanese name of the war means, "Joseon Campaign"; and the Chinese, "the Eastern Pacification".
