Sheikh Mohamed bin Zayed, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the Armed Forces said the UAE colours will be flown with pride today – the country's annual flag day. The <a href="https://www.thenationalnews.com/uae/heritage/2021/08/01/flags-of-the-uae-from-individual-emirates-to-trucial-states-and-the-banner-we-know-today/" target="_blank">UAE flag was created</a> by Abdullah Mohammed Al Maainah, when he was 19, after reading a newspaper article about a contest to design the new nation’s flag. He was inspired by the poet, Safi-u-ddin Al Hali. The four colours on the flag represent Arab unity, as described in poetry written by Al Hali. Fifty years later, Sheikh Mohamed said the flag remains "an enduring display of national unity". "Fifty years ago, a historic design competition was held to choose the flag that would represent our country on the world stage," Sheikh Mohamed said on Twitter. "On the occasion of Flag Day, the UAE flag is flown with pride across each of the seven Emirates in an enduring display of national unity." UAE flag day was first celebrated in 2013 by <a href="https://www.thenationalnews.com/tags/sheikh-mohammed-bin-rashid/">Sheikh Mohammed bin Rashid</a>, Vice President and Ruler of Dubai, to celebrate the accession of <a href="https://www.thenationalnews.com/uae/2021/08/30/president-sheikh-khalifa-establishes-national-human-rights-institution/">Sheikh Khalifa</a> as President of the UAE in 2004.
