North Korea
Japan tried to suppress Korean traditions and culture and ran the economy primarily for its own benefit. Korean resistance groups known as Dongnipgun (Liberation Army) operated along the Sino-Korean border, fighting guerrilla warfare against Japanese forces. Some of them took part in allied action in China and parts of South East Asia. One of the guerrilla leaders was the communist Kim Il-sung, who later became the first leader of North Korea.
First Lady of North Korea
The current First Lady is Ri Sol-ju, wife of Chairman Kim Jong-un, in office since 15 April 2018. In April 2018, Ri's title was elevated to "respected First Lady", the first time since 1974 the title had been used in North Korea, when it was used about Kim Song-ae. Ri was previously called by state media "comrade"; the promotion occurred ahead of the April 2018 inter-Korean summit where Sol-ju and the First Lady of South Korea, Kim Jung-sook, were in attendance.
