Luigi Alidosi (also Ludovico, died 1430) was the lord of Imola (as Papal vicar) from 1391 until 1424, the last ruler of the city from his family.
According to some sources in 1401, his sister Ringarda (Rengarda) who had married the condottiero Andrea Malatesta was suspected of adultery with a nobleman of the Cesenan court named Amerigo Cassini [1] (or Alberigo Casino)and her husband had her locked up in a tower at Bertinoro before sending her back to her family in Imola.
[3] In 1423 Milanese ambassadors intimdated to Alidosi that Filippo Maria Visconti, the Lord of Milan was sending an army to take control of Forli -but that it would be better if Alidosi simply persuaded his daughter to cede Forli into the control of Visconti.
[3] During the Wars in Lombardy, his city was attacked by Filippo Maria Visconti's army, and he was taken captive to Milan.
When he was freed after the end of the conflict, Imola had been acquired by the Papal States: he therefore became a Cistercian monk, and died in Rome in 1430.
