Feudalism in Medieval Europe - Interactive PowerPoints

Students created interactive PowerPoints of the four main levels of society in feudal Medieval Europe--similar to the ones they created for feudal Japan.  Each picture on the pyramid links to a slide where that figure in society gives a first person account of his/her role, including job, description, thoughts/feelings, etc.  The last slide is a Venn Diagram comparing and contrasting the Japanese samurai and European knight.
