During her husband’s 20 years as Philippine president, she amassed a huge collection of art, jewellery, property and – most famously – at least 1,000 pairs of shoes.
Paintings by Van Gogh, Cezanne, Rembrandt, Rafael and Michelangelo; palatial homes in the US and the Philippines; silver tableware, gold necklaces, diamond tiaras – the Marcoses collected the best the world had to offer.
When they were ousted in a “People Power” revolution in 1986, Philippine investigators estimated their wealth at about $10bn (£6.2bn).
The next president, Corazon Aquino, set up a special commission to recover these funds for the government coffers – but now, more than 25 years later, just $4bn has been accounted for.
So what happened to rest of the Marcos collection?
The issue came to the fore again late last year, when Mrs Marcos’ former aide, Vilma Bautista, appeared in a New York court charged with illegally selling a Monet painting.
She was also found to have another three famous artworks in her possession.
The commission admitted that all four were on a list of 146 paintings once owned by the Marcoses which they had not been able to track down.
