Louis I, Duke of Savoy

Louis I (; 24 February 1413 – 29 January 1465) was Duke of Savoy from 1440 until his death in 1465.

Life Louis was born in Geneva, the son of Amadeus VIII, Duke of Savoy and Mary of Burgundy. He was the first to hold the title of Prince of Piedmont.

On 1 November 1433 (or 12 February 1434), at Chambéry, he married Princess Anne of Cyprus, an heiress of the Kingdom of Cyprus and the defunct Kingdom of Jerusalem.

The family resided at Allaman Castle, in the region of Vaud (present-day Switzerland). As Count of Vaud, Louis attempted to conquer the Duchy of Milan, then ruled by the short-lived Ambrosian Republic, but the campaign was unsuccessful.

In 1452, Louis received the Shroud of Turin from Margaret de Charny. The relic remained in the possession of the House of Savoy until 1946, when the Kingdom of Italy came to an end. It was later bequeathed to the Holy See in 1983.

Louis died in Lyon in 1465 while returning from a visit to France.
