After the Second World War, the party was revived and became the second strongest party, behind the Communists. After the latter took power in the 1948 coup d'état, the ČSS's role was reduced to a bloc party. Anti-communist members were persecuted again, forced to exile, or even executed like Milada Horáková. After the Velvet Revolution of 1989, the party failed to regain its importance. Since the 1990s, several splinter parties claim to continue the ČSNS's tradition.
