After Brezhnev brought Czechoslovakia to heel in 1968, Romania and Yugoslavia maintained privileged connections up to the mid-1980s. Ceaușescu adapted the part of Titoism that made reference to the "conditions of a particular country", but merged them with Romanian nationalism and contrasting North Korean Juche beliefs while embarking on a particular form of Cultural Revolution. The synthesis can be roughly compared with the parallel developments of Hoxhaism and found Ceaușescu strong, perhaps unsought, supporters in National Bolshevism theorists such as the Belgian Jean-François Thiriart.
