Sheikh Mohammed bin Zayed Al Nahyan is the Crown Prince of the Emirate of Abu Dhabi. As well as being next in line to the throne, he’s Deputy Supreme Commander of the Emirate’s armed forces. But that’s not why he’s on this list. He’s here because he’s behind Saadiyat Island, a luxury resort featuring the world’s ‘largest single cluster of world-class cultural assets’ (including a Louvre designed by Jean Nouvel and a Guggenheim by Frank Gehry). It’s the artworld’s ultimate exercise in Disneyfication. It’s so big that earlier this year George W. Bush paid a trip to Abu Dhabi to fawn over the models personally. It’s so big that longtime Guggenheim Director Thomas Krens left his post to focus on it. ‘The only expression I can think of to describe it is pharaonic’, he said earlier this year. Not because he was geographically confused, but rather, we’re sure, to demonstrate the true internationalism of the modern museum-brand.
