Martyrs' Day (Arabic: عيد الشهداء) is a Syrian and Lebanese national holiday commemorating the Syrian and Lebanese nationalists executed in Damascus and Beirut on 6 May 1916 by Jamal Pasha, also known as 'Al Jazzar' or 'The Butcher', the Ottoman wāli of Greater Syria. They were executed in both the Marjeh Square in Damascus and Burj Square in Beirut. Both plazas have since been renamed Martyrs' Square.
