itself as an independent commune, dominated by rival mercantile
families. Disordered by these feuds it accepted Count Azzo VI of
Este as its podesta (1208), and made this office hereditary in his
progeny. Este was a small Imperial fief, some forty miles north of
Ferrara, which had been given to Count Azzo I of Canossa by the
Emperor Otho I (961); in 1056 it became the seat of the family, and
soon gave it its name. From this historic house came the later royal
families of Brunswick and Hanover.
From 1208 to 1597 the Estensi ruled Ferrara technically as vassals
of the Empire and the papacy, but practically as independent lords,
with the title of marquis or (after 1470) duke. Under their government
the people prospered tolerably, and supplied the needs and luxuries of
a court that entertained emperors and popes, and supported a notable
retinue of scholars, artists, poets, and priests. Despite lawless
cruelties and frequent wars, the Estensi retained the loyalty of their
subjects through four centuries. When a legate of Pope Clement V
expelled the Estensi and proclaimed Ferrara a papal state (1311),
the people found ecclesiastical rule more irksome than secular
exploitation; they drove out the legate, and restored the Estensi to
power (1317). Pope John XXII laid an interdict upon the city; soon the
people, deprived of the sacraments, began to murmur. The Estensi
sought reconciliation with the Church, and obtained it on hard
conditions: they acknowledged Ferrara to be a papal fief, which they
would rule as vicars of the popes; and they pledged themselves and
their successors to pay, from the revenues of the state, an annual
tribute of 10,000 ducats ($250,000?) to the papacy. `05101
During the long rule (1393-1441) of Niccolo III the house of Este
reached the acme of its power, governing not only Ferrara but also
Rovigo, Modena, Reggio, Parma, and even, briefly, Milan. Niccolo
married as widely as he ruled, having a long succession of wives and
mistresses. One especially pretty and popular wife, Parisina
Malatesta, committed adultery with her stepson Ugo; Niccolo had them
both beheaded (1425), and ordered that all Farrarese women convicted
of adultery should be put to death. When it became clear that this
edict threatened to depopulate Ferrara, it was no longer enforced. For
the rest Niccolo ruled well. He reduced taxes, encouraged industry and
commerce, summoned Theodorus Gaza to teach Greek in the university,
