Sheikh Mohammed bin Zayed bin Sultan Al Nahyan (Arabic: محمد بن زايد بن سلطان آل نهيان‎; born 11 March 1961), colloquially known by his initials as MBZ, is the Crown Prince of the Emirate of Abu Dhabi and Deputy Supreme Commander of the United Arab Emirates Armed Forces. He is seen as the driving force behind the UAE's interventionist foreign policy and is a leader of a campaign against pro-democracy movements in the Arab World. Due to the ill health of the UAE president Sheikh Khalifa bin Zayed, Mohammed bin Zayed was entrusted with most day-to-day decision making of the emirate of Abu Dhabi as the crown prince of Abu Dhabi and most of the presidential public affairs of the state and hence, he is sometimes considered as the UAE's de facto ruler. In 2019, the New York Times named him as the most powerful Arab ruler. In 2020, the New York Times called him "one of the most powerful men on Earth." He was also named as one of the '100 Most Influential People' of 2019 by Time magazine.
