HH Sheikh Zayed Bin Sultan Al Nahyan, who took charge in 1966, saw his Emirate grow, in his 38 years as Amir or Ruler, into the leading role in one of the most prosperous countries in the world, with a $100bn economy. This was not only the beginning of the oil rush which propelled socio-economic expansion on an unprecedented scale; it was also the start of a period of prosperity, peace and growth which reflects his legacy today.
