On this day in history, 9th March 1566, David Rizzio (Riccio), the private secretary of Mary, Queen of Scots, was stabbed to death in front of a heavily pregnant Queen Mary.

But who was David Rizzio and what led to his murder?

John Guy, historian and author of the excellent “My Heart is My Own: The Life of Mary Queen of Scots”, describes David Rizzio as a “young Piedmontese valet and musician, who had arrived in the suite of the ambassador of the Duke of Savoy and stayed on as a bass in Mary’s choir”. Mary obviously took a liking to Rizzio because in late 1564 she chose him to replace her confidential secretary and decipherer, Augustine Raulet, who was a Guise retainer and the only person who Mary had trusted with a key to the box containing her personal papers. Raulet, for some reason, had lost her trust.
