Sheikh Saud Al-Thani’s surprise death has put a renewed focus on Qatar and the country’s ruling Al-Thani family.

The Sheikh and his many relatives were also some of the world’s biggest art collectors of everything from fine art and vintage cars to rare watches. Over the years, in fact, the late Sheikh and his family, Qatar royalty, have spent many billions on art and other collectibles, building an enormous collection that includes the rarest and most magnificent oriental, Islamic, and western contemporary and historical art, as well as an incredibly deep Indian jewelry collection.

Once labelled the “modern-day equivalents of the Medicis,” the family has been applauded for its commitment to collections and the establishment of museums in a region bereft of cultural institutions. They have established the Arab Museum of Modern Art in Doha, I.M Pei’s Islamic Museum of Art, a combined Natural History Museum and Qatar National Library, a Museum of Photography, and a Museum of Clothes & Textiles.

In the wake of the death of Sheikh Saud, at age 48, we thought we would put together a tribute to him listing the top 10 acquisitions that he and the Al-Thani family have acquired. In some cases the prices paid are indeed phenomenal, but what stands out is the diversity of the Sheikh’s interests and undimmed passion for collecting. He was the world’s biggest collector.

1. Paul Cézanne, The Card Players, $250 million
This masterpiece is supposedly the most expensive work ever sold.
