The independent Syrian Arab Republic was founded in 1946. Hafez al-Assad took power in a military coup in 1971 and became President of Syria until his death in 2000. He was succeeded by his son Bashar al-Assad.

In March 2011, protests erupted across the country demanding regime change. The government responded with force and by 2012 the situation had deteriorated into civil war. Opposition groups, including Islamic State, took control of large parts of the country and foreign actors – both for and against the Assad regime – became involved. Russia, Iran, the USA, the UK, the Netherlands and Turkey all engaged in military operations in Syria. Hundreds of thousands of people were killed or ‘disappeared’ in the subsequent years of war. War crimes and crimes against humanity have been widely documented, including the use of chemical weapons. These incidents include the attack on Ghouta in August 2013, in which more than 1,400 people were killed by sarin gas.

At the beginning of December 2024, the Assad regime was suddenly toppled by various armed groups, led by Hayat Tahrir Al-Sham. As of January 2025, armed violence is continuing.

What we’re doing

Every Casualty Counts works with members of the Casualty Recorders Network to support efforts to document every person killed in the Syrian conflict. We have also provided briefings to UN delegates and participated in Human Rights Council debates to promote stronger action on recording casualties in Syria. This led to explicit recognition of the importance of casualty recording in several UN resolutions on Syria.

The work done by casualty recorders in documenting individually verifiable information on each casualty is critical. The process is victim-centred, placing individuals, their families and communities at the centre by ensuring that those killed are not forgotten, and that information is available for accountability-related processes and to access a range of human rights.
