This is the second episode in the series of mini-documentaries based on scientists and their investigation from Malaga University. In this particular video, Angel Galán Sánchez and his research group gives us a realistic and dramatic journey into the fascinating world of the past, with tales of fraud, bribery and embezzlement of public funds. The incredible thing is we are talking about taxation in the Middle Ages and how the feudal society, back then, was characterised by the vesting of legal and economic power in a lord, who was economically supported by mandatory contributions from the peasant population under his jurisdiction and from his landholdings.
