President His Highness Sheikh Khalifa bin Zayed Al Nahyan died earlier today, and the Ministry of Presidential Affairs expressed its condolences to the UAE people, Arab and Islamic nations, and the rest of the globe in a statement on social media.

According to the constitution, vice-president and premier Sheikh Mohammed bin Rashid al-Maktoum, ruler of Dubai, would serve as president until the federal council of the seven emirates meets within 30 days to pick a new president.

For close to a decade the 74 year old president had rarely been seen public after he was diagnosed with stroke.

However, his half-brother Abu Dhabi Crown Prince Mohammed bin Zayed has been the de facto ruler of the U.S.-allied UAE, an OPEC oil producer.

Sheikh Khalifa bin Zayed bin Sultan Al Nahyan is known to be one of the wealthiest  presidents who ever lived.

He someway somewhat controlled over 97.8 billion barrels of oil reserves and was chairman of the Abu Dhabi Investment Authority, which manages $875 billion in assets, the largest amount managed by a nation’s head of state in the world.

Collectively, the Al Nahyan family is believed to hold a fortune of $200 billion dollars.
