After the Ba'athist takeover in 1963, the First Iraqi–Kurdish War intensified and many of the Kurdish guerillas of Kurdistan Democratic Party were sent for treatment to Hungary. This assistance continued under the Second Iraqi–Kurdish War from 1974 to 1975. In the same decade, Patriotic Union of Kurdistan was founded and held close diplomatic ties to the Hungarian Socialist Workers' Party, both being members of the Socialist International. During the Iran–Iraq War, Hungarian ambassadors in Baghdad occasionally reported back to Budapest regarding the situation of the Kurdish guerillas against Saddam Hussein.
