Eternal leaders of North Korea

The eternal leaders of North Korea or eternal leaders of Korea (officially the eternal leaders of Juche Korea) are honorary titles that are posthumously bestowed upon deceased leaders of North Korea. The phrase was used in a line of the preamble to the Constitution, as amended on June 30, 2016, and in subsequent revisions.

It reads (in the original version):

Under the leadership of the Workers' Party of Korea, the Democratic People's Republic of Korea and the Korean people will uphold the Great Leader Comrade Kim Il Sung as the eternal President of the Democratic People's Republic of Korea and Comrade Kim Jong Il as the eternal Chairman of the National Defence Commission of the Democratic People's Republic of Korea[...]
