Kim Bok-dong was among many young women forced into sexual slavery by the Japanese Imperial Army. She later became a Korean human rights activist who campaigned against sexual slavery and war rape. She was one of many young women who were forced into sexual slavery by the Japanese military; a military that systematically recruited girls between the ages of 10 to 18 years of age from colonized and occupied countries from the 1930s until the end of World War II. From age 14, she was imprisoned in comfort stations for eight years across different countries in Asia. Her experiences evoked in her a feminist consciousness and led her to become a strong activist, advocating the end of war-time sexual violence, anti-imperialism, workers' rights, and inter-Korean reconciliation. Along with the other so-called "comfort women", she has made the three-fold demand from the Japanese government: a formal state-level apology, reparations, and correction of Japanese history. In addition, Kim Bok-dong herself also supported other "comfort women" to step forward, and was a leader and spokesperson in the "comfort women" movement. Kim Bok-dong died in Seoul, South Korea, in hospital, on January 28, 2019.

Nangklao or Rama III was the third monarch of Siam under the House of Chakri, ruling from 21 July 1824 to 2 April 1851. He succeeded his father, Rama II, as the King of Siam. His succession was unusual according to the traditions because Nangklao was a son of a concubine rather than that of a queen. His accession was perceived by foreign observers as having usurped the prior claim of Prince Mongkut, who was a legitimate son of Rama II born to a queen, Srisuriyendra. Under the old concept of Thai monarchy, however, a proper king must emulate Maha Sammata in that he must be "elected by the people." Ironically, Prince Mongkut may have later contributed to this misconception, when he feared that his own accession might be perceived by foreign observers as a usurpation.
