To assess a level of realism of the opposition in Poland before the “Solidarity” movement we must first determine its effects. The estimate as modest. Polish opposition members from the 70s failed to effectively influence the public mood to initiate systemic change in the country. There have also developed valuable doctrine, or any political approach to be applicable in a free country. From this perspective, political activities in the 70s was completely devoid of realism. This does not mean, however, that the efforts of this people have gone completely down the drain. The achievements of the opposition in non-democratic system, which was a communist, another measure should be assessed. Undoubted achievements of the five-years activity of several opposition tendencies was to create a new elite that since the birth of “Solidarity” to this day the tone of public life in Poland. It was also planting at different points of the country and different social group the seeds of contention for further life in the communist lie.
