Louis I (Ludovico I or Lodovico I in Italian; 21 February 1413 – 29 January 1465) was Duke of Savoy from 1440 until his death.
The family lived in Allaman Castle, Vaud/Switzerland and as Count de Vaud, Savoy tried to conquer the Duchy of Milan, then under the Repubblica Ambrosiana, but failed.
In 1453 he received the Shroud of Turin from Margaret de Charny. It was held by the House of Savoy until 1946, at the end of the Kingdom of Italy. The Shroud of Turin was bequeathed to the Holy See in 1983. Louis died at Lyon in 1465, while returning from France.
