摘要：Premysliden ruled over the Czech countries (Bohemia, Moravia, and Silesia) more than three hundred years (ca. 930–1306). They cooperated with the ruling houses of the neighboring states (Hungary, Poland, Saxony, Bavaria, Austria etc.) as their political efforts as their marriage policy. The analysis of the Premysliden marriages indicated the existence of the rule of the exogamy, the rule of the preferential matrilateral cross cousin marriage, the rule of the long time systematic exchange of the women among two ruling houses. Example of the Premysliden marriage practice gives the idea of the search of the marriage rules existing in Europe during the early mediaeval centuries.
