The twelfth–century forgeries for monasteries Kladruby and Opatovice in West– and East Bohemia are fascinating texts. These documents were written at the end of the eleventh century and in twelfth century. They recorded the beginnings of these monasteries in series of the deeds, and not in one single act, but all these deeds were in the second half of the twelfth century reshaped in one single document. As such, they are important sources for the establishment of the bonds between the central power and "periphery".
