Endecja was a Polish nationalist movement founded in the early 20th century, primarily associated with the National Democracy party. It aimed to promote Polish nationalism and advocate for the rights of the Polish people, especially in the context of the partitions of Poland. The movement emphasized the importance of a strong national identity and sought to unify various Polish territories. The ideology of Endecja was characterized by its opposition to socialism and its focus on the interests of the Polish nation. It also promoted the idea of a homogeneous Polish state, which sometimes led to tensions with minority groups. The movement played a significant role in Polish politics, especially during the interwar period.
