According to legend, three demi-gods emerged from Samseong,[5] which is said to have been on the northern slopes of Hallasan and became the progenitors of the Jeju people, who founded the Kingdom of Tamna.

One interesting event that took place during these later years of Tamna was the Sambyeolcho Rebellion,[9] which came to a bloody end on Jeju Island in 1274.

[11] In 2006, almost 60 years after the Jeju Uprising, the government of South Korea apologized for its role in the killings and promised reparations.

Perhaps the most distinct cultural artifact is the ubiquitous dol hareubang ("stone grandfather") carved from a block of basalt throughout the island.

The younger generation tends to speak Standard Korean due to the educational system enacted by the South Korean government, which does not allow Jejuan language schools, and has repressed its usage especially during the country's authoritarian era (e.g. under Syngman Rhee, Park Chung Hee and Chun Doo-hwan) up until the 1990s.

[17][18] Ever since the 2000s, the majority of South Korean academic publications had switched to the term "Jeju language" rather than considering it as a dialect.
