The Southeast Asian Games evolved from the South East Asian Peninsular Games or SEAP Games. On 22 May 1958, delegates from the countries in the Southeast Asian Peninsula attending the Asian Games in Tokyo, Japan had a meeting and agreed to establish a sports organization. The proposed rationale was that a regional sports event will help promote cooperation, understanding, and relations among countries in the Southeast Asian region.

Six countries, Burma (now Myanmar), Kampuchea (now Cambodia), Laos, Malaya (now Malaysia), Thailand and the Republic of Vietnam (South Vietnam) were the founding members. The first SEAP Games were held in Bangkok from 12–17 December 1959, with more than 527 athletes and officials from 6 countries; Burma (now Myanmar), Laos, Malaya, Singapore, South Vietnam, and Thailand participating in 12 sports.

In 1977 Brunei, Indonesia, and the Philippines and SEAP Federation changed their name to the Southeast Asian Games Federation (SEAGF), and the games were known as the Southeast Asian Games. (Southeast Asian Games, Wikipedia, 2022)
