Early life Ezzelino was a son of
Ezzelino II da Romano, ruler of
Bassano del Grappa and other fiefs in the Veneto, and Adelaide D'egli Alberti di Mangona, who came from a family of counts in
Tuscany. At the age of four years, he was sent as a hostage to Verona, but nothing else is known about his childhood or education. In 1213, he took part in the siege of the castle of
Este, which belonged to his father's archenemy, marquess
Azzo VI of Este, who died in 1212 and later to his son Aldobrandino. According to the chronicler
Rolandino of Padua, the young Ezzelino already showed a keen interest in siegecraft and acquired a hatred of the Este which would last his entire life.
Rise to power 1226–1239 When Ezzelino II retired to a monastery in 1223, his possessions went to his sons
Alberico, who received the castles and villages in the countryside of Vicenza (including the important centre of Bassano del Grappa) and Ezzelino, who received the possessions in the countryside of Treviso. In 1226 Ezzelino intervened in a factional struggle in Verona, aiding the Monticuli and Quattuorviginti against their enemies, the so-called
pars comitis ("party of the count"), which was headed by the Veronese count
Richard of San Bonifacio. From this time onwards Ezzelino became an important factor in Veronese politics and in 1226-1227 he had become or Lord Mayor of that city. He briefly lost Verona, but regained it in 1230. At this time control over Verona was important because Frederick II was in conflict with the Second
Lombard League, an alliance of cities in
Northern Italy. Whoever controlled Verona could block the
Brenner Pass through the
Alps, and thereby prevent the arrival of reinforcements for Frederick from Germany. Initially, Ezzelino favoured the Lombard League which could block the Brenner and emerge victorious from its first confrontation with the Emperor. However, he and his brother Alberico later changed sides, when it became apparent that the League favoured their enemies in the March, particularly the Este and the San Bonifacio (Sambonifacio). In 1232 the brothers struck an alliance with Frederick and received an imperial privilege of protection. However, four years passed before the emperor could personally intervene in the March of Treviso. The years 1232–1236 were therefore very difficult for Ezzelino and Alberico, who were assailed by many enemies, primarily the San Bonifacio, the Este and the city of Padua. In 1236, Frederick II finally arrived in the March of Treviso. Because Ezzelino and his Veronese allies, the Monticuli and Quattuorviginti, had gained control of Verona in early 1236, the emperor could bring reinforcements across the
Alps, including 3000 German
men-at-arms. In a campaign that began in November 1236 Frederick and Ezzelino, who was becoming an increasingly important ally of the emperor, subjugated all the important cities of the March of Treviso: Vicenza was conquered in November 1236, Padua and Treviso surrendered in February/March 1237. In 1236 Ezzelino married Selvaggia, Frederick's natural daughter who was thirteen years old at the time; conquered
Verona and by treason Padua, seizing the position of
podestà of that city. In Padua he had the monk
Giordano Forzatè arrested and exiled. Ezzelino was one of the protagonists in the Ghibelline-Imperial victory of
Cortenuova (1237) and in 1239 was named Imperial viceroy for the
March of Treviso., and the Romano family became extinct. It was only after his death that the alliance between Sambonifacio and Este fell apart. ==Legacy==
