Ranieri della Gherardesca Nieri

Ranieri della Gherardesca, called Nieri (c. 1252–1325), was a son of Gherardo il Vecchio, beheaded at Naples with Conradin in 1268. Forced to leave Pisa for Sardinia in 1285, he returned to the island in 1294 to lead a Pisan expedition, defeating the sons of his rival Ugolino in 1295.

He hosted Emperor Henry VII at Pisa in 1313 and fought at Montecatini in 1315, where he had himself knighted over the body of Charles of Anjou, nephew of King Robert of Naples.

After his nephew Gherardo il Giovane died suddenly in 1320, Ranieri took charge of Pisa and ruled until his death on 13 December 1325.
