エステ家
The circumstances of Leonello's succession as an illegitimate son fit into the historical context of successions in the House of Este. The history of heirs in the House of Este was distinct from those of other Italian city-states because of the frequency of illegitimate sons being chosen as the future heirs. This also reflects the gender attitudes regarding the political successions in the House of Este during this time period. A greater preference was given for illegitimate sons to become successors, instead of legitimate daughters. Leonello himself was also succeeded by a man who had an illegitimate birth status. His brother, Borso, who was born from the same mother of Leonello, was later chosen to be Leonello's successor.
