The Piast Concept is a political idea of the Polish state based on its initial territories under the Piast dynasty, containing a mostly Polish population. It holds that Poland, composed of primarily Polish parts in the West during the Middle Ages, was a solid Westernized state and was equal to other Western European countries.
For its supporters, the Piast Concept is mainly identified with Westernization, attachment to Europe and its ideas, close relationship with Western countries, and pragmatism in international relations while avoiding unwise adventures in the East.
