samizdat

"Because the state proved itself unwilling to reform, samizdat began to
focus on alternative political systems. Within samizdat, several works
focused on the possibility of a democratic political system. Democratic samizdat possessed a revolutionary nature
because of its claim that a fundamental shift in political structure was necessary to reform the state, unlike socialists who hoped to work
within the same basic political framework to achieve change."
