The <em>Medieval era</em> or <em>Middle Ages</em> refers to the period in European history between the collapse of the Roman Empire and the Renaissance, characterized by being turbulent and violent, due to numerous invasions, and also by social systems such as <em>Feudalism</em>, which granted nobles the use of the King's land in exchange for loyalty.
Hence conflict between lords was usual, thus <em>loyalty</em>, <em>protection</em> and <em>honor</em> were essential medieval values, and crucial in the development of the social <em>Code of Chivalry</em>, a set of skills and manners belonging to the upper classes, where <em>Knights</em> protected lords and ladies, considered brittle or fragile, which aggravated <em>social inequality</em> since such rules only applied to certain social groups.
