Editing Piombino (section)

===Lordship of Piombino===
The Castle of Piombino remained a Pisan possession until [[Gerardo Appiani]], after ceding Pisa to the [[Visconti of Milan|Milanese Visconti]], carved out an [[Principality of Piombino|independent lordship]] centred on Piombino that included the islands of the [[Tuscan Archipelago]]: [[Elba]], [[Pianosa]], [[Montecristo]], [[Capraia]], [[Gorgona (Italy)|Gorgona]], and [[Isola del Giglio|Giglio]], for his family, who held the state intermittently until 1634.

In 1445, through his marriage with Caterina Appiani, [[Rinaldo Orsini (condottiero)|Rinaldo Orsini]] acquired the Lordship of Piombino. In 1501–1503 the lordship came under the control of [[Cesare Borgia]]. After [[Cosimo I de' Medici]] had occupied the Lordship of Piombino in the course of the war against [[Republic of Siena|Siena]], in 1553 and 1555 a French-[[Ottoman Empire|Ottoman]] fleet attacked Piombino, but was pushed back. In 1557, a peace treaty reinstated the Appiani as rulers of Piombino, with the exception of [[Portoferraio]], which was given to the [[Grand Duchy of Tuscany]], and the area of [[Orbetello]], which became part of the [[State of the Presidi]] under Spanish control.
