Early lifeEdit

Laura was born in Fano to Cardinal Mazarin's eldest sister, also named Laura, and her husband Count Girolamo Martinozzi da Fano, a Roman noble of an ancient family.

She was one of the Mazarinettes: the seven nieces of the Cardinal, that he brought to France in order to arrange for them rich and politically advantageous marriages, including Hortense and Olympia Mancini. For two years Laura lived in France under the guardianship of her uncle and "quasi stepmother", Anne of Austria.

Duchess of ModenaEdit

On her sixteenth birthday, 27 May 1655, she was married to the Duke of Modena, Alfonso IV d'Este. The wedding by proxy occurred at the Palace of Compiègne with the Count of Soissons acting as the Duke of Modena. They had three children, two of which survived infancy.

Regent of ModenaEdit

Upon the death of her spouse in 1662, she became regent of Modena during the minority of her son, Francesco d'Este, Duke of Modena. She discontinued her regency in 1674.

Later lifeEdit

Laura was abandoned by her son[citation needed] The mentally and physically weak Francesco II came under the influence of his half-brother Cesare, and thus Laura moved to Rome with her mother.

She died in Rome in 1687, shortly before the birth of her grandson, James, Prince of Wales. She was buried in the Este chapel of the Church of San Vincenzo at Modena.[citation needed]
