He is known for his adventurous side, and is often seen taking part in adrenalin-pumping activities such as skydiving, free diving and has even scaled the Burj Khalifa.
He has shared several glimpses into his life as a father with his 14.9 million Instagram followers over the past 18 months, including introducing his children to his beloved horses at F3 Stables during a summer trip to the UK, and taking them out for a cycle alongside his father, Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai.
Sheikh Hamdan often shares throwbacks to his own childhood on Instagram too, stressing the importance of family to him. From childhood ski trips to desert adventures, his Instagram feed is full of plenty of nostalgic childhood memories from the UAE and afar.
Why do we call Sheikh Hamdan 'Fazza'?
Like his father, Sheikh Hamdan writes poetry, which he sometimes shares online.
Fazza means "a person who speeds to the help and support of others". From the Emirati dialect, it's a term often used in Nabati poetry, which is a common art form in the UAE.
Sheikh Hamdan has described his poetry as "my identity and poetic character through which I humbly attempt to rekindle joy in the hearts of people, alleviate their suffering in my own simple way. I express their hopes and aspirations."
