…Jeju Island, which the rebels capture, banishing the king of Tamna in November 1271.

The Sambyeolcho had laid low until the end of 1271, during which time, they had sought help from the Japanese Kamakura Shogunate.

Regained their strength to some degree the following year, they repeatedly loot the Korean coast.

A combined Goryeo-Mongol assault begins in February 1272, and crushes the rebels in April.

Hereafter, the Mongols will directly controlled the Tamna kingdom until 1294.

After a visit to Manila, Lapérouse sets out for the northeast Asian coasts the next year, on April 9, 1787.

He sees the island of Quelpart, in the Korean Peninsula, (present-day Cheju in South Korea), which had been visited by Europeans only once before when a group of Dutchmen shipwrecked there in 1635.

He visits the Asian mainland coasts of Korea.

...on faraway Jeju Island and ...

On April 3, 1948, the police on Jeju island fire on a demonstration commemorating the Korean struggle against Japanese rule.

Outraged, the people of Jeju attack 12 police stations.

In the fighting, up to 100 policemen and civilians are killed.

Rebels also burn polling centers for the upcoming election and attack political opponents and their families.

They then issue an appeal urging the local population to rise against the American military government.

The Workers Party of South Korea and their appeal find sympathy among the local population due to the prevailing sentiment that the local government and police forces had collaborated with the Japanese occupation of Jeju and unrest caused by heavy taxation of agricultural commodities.

Seeking a speedy resolution to the insurrection, the South Korean government sends 3,000 soldiers of the South Korean 11th Constabulary Regiment to reinforce local police, but on April 29 several hundred soldiers mutiny, handing over large small-arms caches to the rebels.

The Seoul government also sends several hundred Northwest Youth Association members, a group of anticommunist North Korean refugees, as part of a paramilitary force.

The Northwest Youth Association become notorious for killing male Jeju residents and then forcing the victim's female family members into marriage arrangements with Northwest Youth members so that they would inherit their land.

Lt. General Kim Ik Ruhl, commander of the South Korean force on the island, attempts to end the insurrection peacefully by negotiating with the rebels.

He meets several times with rebel leader Kim Dalsam (South Korean Worker's Party Member) but neither side can agree on conditions.

The government wants what amounts to a complete surrender and the rebels demand disarmament of the local police, dismissal of all governing officials on the island, prohibition of paramilitary youth groups on the island and reunification of the Korean peninsula.

General Kim Ik Ruhl is suddenly recalled to Seoul over his conciliatory approach with the rebels and is surprised when his replacement mounted a sustained offensive against the rebels by the end of the summer.

The Jeju guerrillas create base camps in the mountains and the government forces hold the coastal towns.

Farming communities between the coast and the hills become the primary battle zone.

By October 1948, the rebel army consists of approximately 4,000 combatants, and although many are poorly armed, they score a number of minor victories over the Army.

In late fall of 1948 the rebels begin openly siding with the North Koreans by flying North Korean flags.

On November 17, 1948, the Syngman Rhee regime proclaims martial law in order to quell the rebellion.

One report from December 1948 describes how South Korean soldiers assaulted Jeju villages and took away young men and girls.

The young men were executed, and girls were also executed after they had been gang-raped over two weeks.

By one estimate seventy percent of Jeju island villages were burned by the troops.
