Abstract
A state’s sovereignty is its exceptional value and also an international
legal feature that distinguishes it among other states because it decides on its
independence and self-reliance. A sovereign state is a state that carries out
its own unlimited – with the exception of legal and international alliances’
limitations – internal and foreign policy. The article is an attempt to show
the influence of the Polish accession to the European Union on its national
sovereignty. The author asks many interesting questions, suggests theses and
hypotheses and tries to show that the voluntary membership of the European
Union was necessary and inevitable, and that it strengthens Poland’s sovereignty
and serves the Polish national interest. He also shows that the European
Union, if it wants to play an important role in the new political order, must
evolve from an economic and financial union into a strong federation of
national states that will include a fiscal, banking, social, political and military
union.
