The federation was founded on 28 November 1946 by Christians who had joined the ranks of the new communist administration.
Immediately, it declared that it would support the country's leaderKim Il-sung and oppose the formation of the South Korean state. Back then, the organization was led by Kim Il-sung's mother's cousin Kang Ryang-uk. Although Christians in North Korea were mostly anti-communist, about third of them joined the Korean Christian Federation. Christian leaders who refused to join were imprisoned.
The federation is "under close government supervision". The federation itself restricts certain Christian activities.
Officially, the institution comprises 10,000 North Korean Christians, and acts as an inter-denominational organization by playing an important liaison role between the government and the Christians. It is one of three official Protestant bodies recognized in the country.
