The last 10 years of the 20th century can surely be perceived as one of the most important decades of Polish history. Following the political decisions taken by the Poles in 1980 (the establishment of ‘Solidarity’) and 1989 (the Round Table, and semi-free election), on 29 December 1989 – by amendment of the old Constitution 1952 – Poland rejected the political and economic system introduced after World War II. By breaking free from the totalitarian socialist state, Poland pronounced its support for a democratic state of law that fulfils principles of social justice. By rejecting the centrally-planned state economy it chose market-oriented economy based on freedom of economic activity and ownership guarantee. Finally, by breaking free from the Soviet block it insisted on its return to a European community based on values of democracy, rule of law, national identity and peaceful cooperation of independent states.
