internal discord allowed Uguccione della Faggiuola of Pisa to make himself lord of Lucca. The Lucchesi expelled him two years later, and handed over the city to another condottiere Castruccio Castracani, under whose rule it became a leading state in central Italy. Lucca rivalled Florence until Castracani's death in 1328. On 22 and 23 September 1325, in the battle of Altopascio, Castracani defeated Florence's Guelphs. For this he was nominated by Louis IV the Bavarian to become duke of Lucca. Castracani's tomb is in the church of San Francesco. His biography is Machiavelli's third famous book on political rule. In 1408, Lucca hosted the convocation intended to end the schism in the papacy. Occupied by the troops of Louis of Bavaria, the city was sold to a rich Genoese, Gherardino Spinola, then seized by John, king of Bohemia. Pawned to the Rossi of Parma, by them it was ceded to Martino della Scala of Verona, sold to the Florentines, surrendered to the Pisans, and then nominally liberated by the emperor Charles IV and governed by his vicar. Lucca managed, at first as a democracy, and after 1628 as an oligarchy, to maintain its independence alongside of Venice and Genoa, and painted the word Libertas on its banner until the French Revolution in 1789.
Napoleonic conquest
Lucca had been the second largest Italian city state (after Venice) with a republican constitution ("comune") to remain independent over the centuries.
In 1805, Lucca was conquered by Napoleon, who installed his sister Elisa Bonaparte Baciocchi as "Queen of Etruria".
After 1815 it became a Bourbon-Parma duchy, then part of Tuscany in 1847 and finally part of the Italian State
