The world was a very different place five years ago.
We had only just discovered the tablet and the iPhone 4 was the hottest smartphone on the market. We said farewell to Harry Potter and hello to the first episode of Game of Thrones. Julia Gillard was Prime Minister of Australia, and Instagram was only just getting started.
And more importantly, five years ago, Syria was bustling with vibrant communities, commerce and culture. But that all changed on 15 March, 2011, when Syria began its descent into the deadliest conflict of our time.
If five years has felt like a long time in the world of pop culture and politics, it’s literally been a lifetime for 3.7 million Syrian children who were born during the brutal conflict.
One in three of all Syrian children alive today have never known a world without war. Meet just a few.
