Samir Nashar is the president of the Secretariat General of the Damascus Declaration alliance and its representative in the Executive Committee of the Syrian National Council.

Nashar became an active dissident during the Damascus Spring (2000), a period of social and political debate following the death of Hafez al-Assad. He was a founding member of the al-Kawakibi discussion forum in Aleppo, named after the early-twentieth-century advocate of an Arab renaissance, Abdul Rahman al-Kawakibi, and also joined the Committee to Revive Civil Society.

Nashar was arrested for the first time in 2003 and for a second time in 2006 after being named spokesperson of the Syrian Free National Party and participating in an opposition meeting in Washington D.C.

Born in Aleppo in 1945, Nashar studied business and economics and worked in the business sector in Aleppo. He left Syria at the end of 2011 and is currently in exile in Istanbul.
