From the various sources of historical readings (I am not able to keep up with all the different books that Tiger has been reading on his own), Tiger has known about the Franks even before we started on this topic.

To understand more of what happened during this period, we also watched the following documentary:
Tiger rounded the topic off by reading two historical fictions on this subject:
