Card 1definition

Question

What was Sedo politics?

Answer

A system in early-to-mid 19th century Korea where powerful in-law clans (families married into the royal family), especially the Andong Kim clan, controlled the government instead of the king.

Card 2concept

Question

Who founded Donghak, and when?

Answer

Choe Je-u founded Donghak ('Eastern Learning') in 1860, blending Confucian, Buddhist, Daoist and shamanist ideas.

Card 3definition

Question

What was the core radical teaching of Donghak?

Answer

'Innaecheon' — the idea that all people carry heaven within them and are equal before heaven, a direct challenge to Korea's rigid class hierarchy.

Card 4example

Question

What happened to Choe Je-u?

Answer

He was arrested and executed by the state in 1864 for spreading what officials saw as dangerous heterodox teaching, but Donghak survived among peasants.

Card 5concept

Question

Who was the Daewongun and when did he rule?

Answer

Yi Ha-eung, father of the boy-king Gojong; he ruled as regent from 1863 to 1873.

Card 6process

Question

Name three domestic reforms of the Daewongun.

Answer

Broke the in-law clans' grip on government posts, reduced yangban tax exemptions, and closed about 600 of Korea's 700 seowon (private academies).

Card 7example

Question

What foreign incursions did the Daewongun repel, and when?

Answer

French forces in the Byeong-in yangyo (1866) and American forces in the Shinmiyangyo (1871), earning Korea the nickname 'Hermit Kingdom'.

Card 8process

Question

What triggered the Treaty of Ganghwa?

Answer

In 1875 the Japanese warship Unyo deliberately provoked Korean coastal defences near Ganghwa Island; Korea's return fire gave Japan its pretext to force a treaty in 1876.

Card 9definition

Question

What did the Treaty of Ganghwa (1876) require?

Answer

Korea opened three ports to Japanese trade, granted Japanese citizens extraterritoriality, had no tariff control over Japanese goods, and was declared 'independent' (undermining Qing suzerainty claims).

Card 10comparison

Question

Compare the Daewongun's and Queen Min's approach to foreign powers.

Answer

The Daewongun pursued strict isolation and rejected all foreign contact; Queen Min's faction, once in power, favoured cautious reform while maintaining close ties to Qing China ('Sadae').

Card 11concept

Question

Who led the Gapsin Coup and what did it demand?

Answer

Kim Ok-gyun led the pro-Japanese 'Enlightenment Party' reformers in December 1884; their 14-point programme demanded abolishing class privilege, tax reform, and cutting tribute ties to Qing China.

Card 12process

Question

Why did the Gapsin Coup fail, and what was the result?

Answer

It lasted only three days before Qing troops garrisoned in Seoul crushed it; the result was tightened Qing control over Korea for the next decade and worsened Korea-Japan relations.
