In the Middle Ages justice was conceived differently by each individual according to his ability to use it for his or her own benefit. For ‘powerful people’ (powerful personae), justice was an instrument of power, and when it did not serve its objectives, they were willing to go against her, disregarding her mandates. The kings were the main perpetrators of this type of behaviour, claiming political power outside the judiciary based on their real absolute power. The common population conceived legality as a defence instrument against the most powerful, but was equally sensitised. This work analyses some of the forms of disrespect for justice and the abuses of power that had the greatest impact on the city of Toledo from the time of its Christian conquest to the establishment of the ‘closed regimen’, highlighting the interrelationship between the phenomena of political marginalisation, economic coercion, ideological control, civil violence, judicial disobedience, etc., in the urban area of Medievo.
