Isabel Luísa was the only child of Peter II of Portugal and his first wife, the French born Princess Marie Françoise of Savoy. She was born at the Ribeira Palace, Lisbon, in 1669.[citation needed]

Marriage prospectsEdit

It was planned that she would marry Victor Amadeus II of Savoy, a first cousin through her aunt Marie Jeanne, Duchess of Savoy, then regent for her son. The marriage was opposed by most of the Savoyard court as it meant that Victor Amadeus would live in Portugal and his mother would remain in power. But that plan was not implemented.

Other proposed candidates included Gian Gastone de' Medici (future Grand Duke of Tuscany), le Grand Dauphin son of Louis XIV, Charles II of Spain, the Duke of Parma as well as a Count Palatine of Neuburg.[citation needed] Nothing came of these plans. For this she was nicknamed Sempre-noiva, "Always-engaged".

Death and burialEdit

She died of smallpox at Palhavã in 1690, when she was 21 years old. Isabel Luísa is buried at the Monastery of São Vicente de Fora in Lisbon after being moved from the Convent of the Francesinhas.
