Kim Yong-nam (born 4 February 1928) is the North Korean Chairman of the Presidium of the Supreme People's Assembly, a position held since 1998. He was elected a member of the presidium of the politburo of the central committee of the Workers' Party of Korea in 2010.

He was born in the Central District, Heijo (now called Pyongyang), on February 4, 1928. After graduating from a university, he worked as a teacher at the central party School, vice-department director of the WPK Central Committee, vice-minister of foreign affairs, and first vice-department director, department director and secretary of the WPK Central Committee, vice-premier of the administration council and concurrently minister of Foreign Affairs.

As chairman of the Presidium, he is considered the de facto head of state of North Korea. Although he is not de jure head of state of North Korea (as no such office exists), he accepts the credentials of ambassadors, conducts foreign relations and signs treaties. He has held this office since 5 September 1998, and he previously served as foreign minister from 1983 to 1998. Kim represents North Korea on all state visits and receives visiting heads of state. In theory, he, Premier Choe Yong-rim, and National Defense Commission Chairman Kim Jong-un form a tripartite executive, each having powers equal to a third of a president's in Presidential systems, controlling foreign relations, government and domestic affairs, and defense, respectively. In practice, Kim Jong-un, like his father, Kim Jong-il, before him, exercises absolute control over the country, and the Chairman of the Presidium is considered a junior position.

Kim Jong-un also romanised as Kim Jong-eun or Kim Jung-eun, (born 8 January 1983 or 1984), is the current supreme leader of North Korea. He has held the titles of the First Secretary of the Workers' Party of Korea, the Chairman of the Central Military Commission, First Chairman of the National Defence Commission of North Korea, the Supreme Commander of the Korean People's Army, and also a presidium member of the Central Politburo of the Workers' Party of Korea. He was officially declared the supreme leader following the state funeral for his father, Kim Jong-il on 28 December 2011. He is the third and youngest son of his deceased predecessor Kim Jong-il and his consort Ko Young-hee. From late 2010, Kim Jong-un was viewed as heir apparent to the leadership of the nation, and following his father's death, he was announced as the "Great Successor" by North Korean state television. At Kim Jong-il's memorial service, North Korean Chairman of Congress Kim Yong-nam declared that "Respected Comrade Kim Jong-un is our party, military and country’s supreme leader who inherits great comrade Kim Jong-il’s ideology, leadership, character, virtues, grit and courage". On 30 December 2011 the Politburo of the Workers' Party of Korea formally appointed Kim as the Supreme Commander of the Korean People's Army. On 11 April 2012, the 4th Party Conference elected him to the newly-created post of First Secretary of the Workers' Party of Korea.

Roh Moo-hyun (Hangul: 노무현; Hanja: 盧武鉉; Korean pronunciation: [no mu hjʌn]) GOM (1 September 1946 – 23 May 2009) was the 16th President of South Korea (2003–2008).

Roh's pre-presidential political career was focused on human rights advocacy for student activists in South Korea. His electoral career later expanded to a focus on overcoming regionalism in South Korean politics, culminating in his election to the presidency. He achieved a large following among younger internet users, particularly at the website OhMyNews, which aided his success in the presidential election.

Roh's election was notable for the arrival in power of a new generation of Korean politicians, the so-called 386 Generation, (i.e. people in their thirties when the term was coined, who had attended university in the 1980s, and who were born in the 1960s). This generation had been veterans of student protests against authoritarian rule, and advocated a conciliatory approach towards North Korea, even at the expense of good relations with the USA.

Koreans in Japan are the ethnic Korean residents of Japan. They currently constitute the second largest ethnic minority group in Japan. The majority of Koreans in Japan are Zainichi Koreans, also often known as Zainichi (在日) for short, who are the permanent ethnic Korean residents of Japan. The term "Zainichi Korean" refers only to long term Korean residents of Japan who trace their roots to the period of Japanese colonialism in Korea, distinguishing them from the later wave of Korean migrants who came mostly in the 1980s.

The Japanese word "Zainichi" itself means "staying in Japan", and implies temporary residence. Nevertheless, the term "Zainichi Korean" is used to describe settled permanent residents of Japan, both those who have retained either their Joseon (old, undivided Korea) or South Korean nationalities, and even sometimes includes Japanese citizens of Korean descent who acquired Japanese nationality by naturalization or by birth from one or both parents who have Japanese citizenship.
