Without question the most significant development of the formative era of Poland's history was the gradual absorption of the country into the culture of medieval Europe. After their relatively late arrival as pagan outsiders on the fringes of the Christian world, the Western Slavs were fully and speedily assimilated into the civilization of the European Middle Ages. Latin Christianity came to determine the identity of that civilization and permeate its intellect and creativity. Over time the Central Europeans increasingly patterned their thought and institutions on Western models in areas of thought ranging from philosophy, artistic style, literature, and architecture to government, law, and social structure. The Poles borrowed especially heavily from German sources, and successive Polish rulers encouraged a substantial immigration of Germans and Jews to invigorate urban life and commerce. From its beginning, Poland drew its primary inspiration from Western Europe and developed a closer affinity with the French and Italians, for example, than with nearer Slavic neighbors of Eastern Orthodox and Byzantine (see Glossary) heritage. This westward orientation, which in some ways has made Poland the easternmost outpost of Latinate and Catholic tradition, helps to explain the Poles' tenacious sense of belonging to the "West" and their deeply rooted antagonism toward Russia as the representative of an essentially alien way of life.
