The evolution of the resulting harshness of purges in Czechoslovakia, like much of its history after 1948, was a function of the late takeover by the communists, with many of the purges focusing on the sizable numbers of party members with prior memberships in other parties. The purges accompanied various show trials, including those of Rudolf Slánský, Vladimír Clementis, Ladislav Novomeský and Gustáv Husák (Clementis was later executed). Slánský and eleven others were convicted together of being "Trotskyist-zionist-titoist-bourgeois-nationalist traitors" in one series of show trials, after which they were executed and their ashes were mixed with material being used to fill roads on the outskirts of Prague.
