Grosso Agontano - Republic 2d Period

Bologna's second republican period followed the expulsion of the Papal legate in 1376 — part of the broader War of the Eight Saints, in which Florence bankrolled a league of Italian communes against Gregory XI. The Bolognese mint resumed civic coinage almost immediately, reasserting communal authority through silver issues that had been suppressed under direct papal administration.

The agontano type itself derived from Ancona's grosso, adopted and adapted across central Italy during the 13th century as a regional commercial denomination before individual communes began asserting their own monetary identities through it.
