The Medici family, recognized as the House of Medici, first gained wealth and political influence in Florence during the 13th century through their achievements in commerce and banking.
The Aztecs, a significant Meso-American civilization, exhibited a complex social structure. Their society consisted of three tiers: the upper class, initially not hereditary but eventually becoming so, enjoyed improved access to education and resources. The second tier comprised peasants who worked as farmers, warriors, artisans, and tradespeople. The lowest class consisted of slaves, who could be war captives, individuals in debt, or criminals, but occasionally had the opportunity for freedom in captivity through various means, such as marrying their owners, purchasing their freedom, or having children.
