Olympia Mancini, Countess of Soissons

Olympia Mancini, Countess of Soissons (French: Olympe Mancini; 11 July 1638 – 9 October 1708) was the second eldest of the five celebrated Mancini sisters, who along with two of their female Martinozzi cousins, were known at the court of King Louis XIV of France as the Mazarinettes because their uncle was Louis XIV's chief minister, Cardinal Mazarin. Olympia was later to become the mother of the famous Austrian general Prince Eugene of Savoy. She also involved herself in various court intrigues including the notorious Poison Affair, which led to her expulsion from France.

Family and early years
