#YouPromised campaign

Theirworld and magician Dynamo travelled to Lebanon to meet Syrian kids who have been left out of school and let down by world leaders. With more than 680,000 still waiting to go to school, we released a powerful film telling their stories.

Theirworld launch a series of short films filmed by Syrian refugee children to tell the story of their lives, using video cameras that we gave them six months earlier. Watch Asmah, Bassam, Rojin and Mustafa tell their stories.

Ahead of a major meeting of world leaders in Brussels, Theirworld supporters send message telling them to keep the promise to the more than 500,000 Syrian refugee children who are still out of school despite the major progress we've seen for so many of their would-be classmates.

The conference hosts re-commit to their goal of "getting all refugee children and vulnerable host children in quality education" - and pledge $6bn to the overall humanitarian response.

The co-hosts of the London conference deliver a report on funding progress and promise to track the pledge to get all refugee children in school.

UN education envoy Gordon Brown tells a UK parliamentary inquiry:  “We’re still one million kids short. We’re still $1 billion short." Another Syria is announced, to be held in Brussels in April.

A Theirworld report says 370,000 Syrian refugee girls - more than 60% of girls under 18 - living in Turkey are out of school. It says action is needed to overcome gender barriers.

The Syria conference co-hosts hold an update meeting. Theirworld President Sarah Brown tells them more than 30,000 messages have been sent to them on social media.

Alexandra Kensland Letelier, one of A World at School's network of Global Youth Ambassadors, delivers more than 18,000 messages in Norway, one of the co-hosts of the Syria conference.

We produce a video to remind countries of their broken promise - and to urge people to send out a message that this is unacceptable.

The new school year is about to start but half of all Syrian refugees could still be out of school. Theirworld asks supporters to post messages on the Facebook pages of co-hosts United Kingdom, Norway, Germany, United States and Kuwait.

With 60 days to go before the school year starts in the region, Theirworld launches the #YouPromised campaign. We publish a report that reveals an urgent funding gap, with less than $400,000 of the $1.4 billion pledged at the conference having materialised.

World leaders meeting at the Supporting Syria and the Region conference in London promise to provide the funding to get one million Syrian children in school during the 2016-17 academic year.
