The West Slavic and Lechitic peoples as well as any remaining minority clans on ancient Polish lands were organized into tribal units, of which the larger ones were later known as the Polish tribes; the names of many tribes are found on the list compiled by the anonymous Bavarian Geographer in the 9th century. In the 9th and 10th centuries, these tribes gave rise to developed regions along the upper Vistula, the coast of the Baltic Sea and in Greater Poland. The latest tribal undertaking, in Greater Poland, resulted in the formation of a lasting political structure in the 10th century that became the state of Poland.
