Kim Yong Seob (Korean: 김용섭 [gim-yong-seop]; 8 October 1931 - 20 October 2020) was a South Korean scholar, historian, and honorary professor at Yonsei University.
 Kim is known for influencing change in Korea. Korea was seen as a country whose development was due to colonization. Kim showed how capitalism was already changing Korea. Through nine books and over fifty years, his research on agricultural history from the late Joseon period to modern Korea explores how Joseon could develop and sustain a capitalist society.
 He was awarded the first Korean Studies Literature award with his nine books.
 Kim's work used extensive data and a variety of evidence to document Joseon's transformation move into a capitalist society, showing that Japanese colonization was not needed to accelerate the process. Because Joseon was a Japanese colony, the history of Joseon was written by the Japanese. Through “intrinsic development theory” (“내재적 발전론”[nae-jae-jeok bal-jeon-ron]), he argued that Japanese colonialism was not responsible for the development Joseon, as the Japanese had claimed in their colonial histories.
 Kim was born in Tongcheon, Gangwon-do in 1931 when Korea was a colony of Japan. Before the Korean war, he moved to the southern part of Korea.
 He graduated from the Department of History at Seoul National University and devoted his entire life to researching the agricultural history of the late Joseon. He was obsessed with the intrinsic development process of Korean history. Through systematic historical research on agriculture in Korea, the intrinsic development of Korea was recognized and influenced academia and Korean society.
 From 1959 to 1975, he served as a professor at Seoul National University and moved to Yonsei University in 1975. He retired from Yonsei University in 1997. After reaching retirement age in 1997, he became a member of the Korean Academy of Sciences. Following his retirement in 2000, Kim Yong Seob also became an honorary professor at Yonsei University. He received the National Medal of Merit Dongbaek (1997) and the Chiam Academic Award (1984).
 In the 1960s, popular articles were published in newspapers and magazines about him, but as time passed, Kim Yong Seob's health was deteriorating, so he had to choose either work or publicity. Kim Yong Seob chose to continue his research rather than show himself in front of the public.
 Kim Yong Seob's health declined and he passed away on 20 October 2020.
 Kim Yong Seob commenced his study of Korean agricultural history after completing an undergraduate degree in history at Seoul National University and graduate school at Korea University. He said, "It was judged that the class confrontation between the farmers and yangbans (양반) before the Japanese colonial rule was expanded after liberation." As a displaced person, he paid great attention to overcoming the division of the country and tried to explain the internal causes of the Korean War. As it was necessary to understand the socioeconomic background of the war of ethnic conflict, his research on agricultural history focused on the social conflict between landlords and farmers in the agriculturally oriented society of Joseon.
 Kim Yong Seob's view of the Korean War is also distinct from the theory of civil war in the Korean War claimed by progressive American scholars. This theory holds that the U.S. amplified the social conflict in the Korean Peninsula rather than resolving it, which eventually led to war. In contrast, Kim Yong Seob believes that the conflict between landlords and farmers in Korean rural areas, which had accumulated since the late Joseon, led to a confrontation between capitalist and socialist under Japanese colonial rule, and the conflict exploded.
 His research on Korean agricultural history focuses on socioeconomic history to explain agricultural technology, land systems, farmers, landlord management, social change, and contradictory structure and economic history research to agonize and sought solutions to agricultural problems at the time.
 Extrapolating from his research, he contended that if society in the late Joseon had not been influenced by foreign powers, it could have developed into a capitalist society on its own. Kim Hyung Seob refers to this as “intrinsic development”. Careful analysis of the land ledger, Yangan (양안), and the family register determined that the “well-to-do tenant farmers” (경영형 부농) were growing in the late Joseon. Wealthy farmers who held managerial positions were a new force that played a major role in transforming the economy. His research shook off the colonial theory that the Korean people had no power to independently make history and needed to be ruled by foreign powers. Furthermore, it was evaluated that his research contributed to making Koreans confident by providing a positive spirit.
 Kim Yong Seob's research on modern and contemporary agriculture can be referred to as "two paths to modernization": landlord modernization and peasant modernization. Kim Yong Seob saw that the choice of modernization path is determined by how agricultural and rural problems are solved. In South Korea, it was found that the landlord modernization path, in which landlords became industrial capitalists, and the peasant modernization path, in which farmers grew into citizens, were repeatedly compromised and confronted. The foreign scholar who identified the various stages in the process of forming a modern state (in the context of rural changes) is Barrington Moore, author of the Social Origins of Dictatorship and Democracy. There are many differences between Barrington Moore and Kim Yong Seob's research, but comparing the two will greatly help to understand contemporary Korean history in a comparative historical context.
 Kim Yong Seob's research on agricultural history is a huge academic achievement accomplished by the liberation generation. This generation experienced the tragedies of colonialism, division, and war. His work represents the history of knowledge that the liberated generation struggled with during their era. In addition, his work could help today's generation, as it continues to work through the problem of division and the task of overcoming spiritual colonialism.
 In The Twilight of Modern History, Yun Hae Dong said:
 Criticism from Kim Ho Gi:
 Some see the theory of intrinsic development as a product of nationalism's desire to exaggerate the history of the great development of the people to compensate for the inferiority complex that comes from being trampled on by foreign powers. However, Kim Yong Seob's aim is to look at the dark wounds of the nation from the front and try to find the cause from the inner background without blaming others.
 Kim Yong Seob received many awards, including:
