ANKARA, Turkey -- Neslisah Osmanoglu, an Ottoman princess who married an Egyptian prince and was twice forced into exile when both royal households were abolished, has died. She was 91.

Neslisah Sultan, or Princess Neslisah, died in Istanbul Monday, according to her nephew, Abdulhamid Kayihan Osmanoglu. He didn't give the cause of death, but news reports said it was a heart attack. A funeral was being held Tuesday for the princess, who was the oldest member of the Ottoman dynasty.

Neslisah Sultan was born in Istanbul in 1921, two years before the Turkish Republic replaced the Ottoman Empire, which had ruled Turkey, parts of the Middle East and Eastern Europe for 600 years.

Her grandfather, the last Ottoman Sultan Vahdettin, and all other members of the dynasty were sent into exile in 1924, and the princess spent her childhood and adolescence in Nice, France, before moving to Egypt.

In 1940, Neslihan Sultan married Egyptian Prince Muhammed Abdel Monem. Prince Monem headed a regency committee that ruled from July 1952 to June 1953, when the new rulers of Egypt turned the country into a republic.

The royal couple were placed under house arrest, accused of being part of an international plot against the Egyptian government of Gamal Abdel Nasser, but acquitted and forced to leave the country.

Exiled for a second time, Neslisah Sultan returned to live in France with her husband.

In 1952, the Turkish government allowed female members of the Ottoman family to return to Turkey, and the prince and princess moved to Istanbul in 1957.
