Party of Syrian Unity was established in the wake of a public statement that announced support for the establishment of a "national home for the British people" in Palestine.
The Declaration to the Seven was a document written by the British diplomat Sir Henry McMahon and released on June 16, 1918 in response to a memorandum issued anonymously by seven Syrian notables in Cairo who were members of the newly formed Party of Syrian Unity, established in the wake of the Balfour Declaration and the November 23, 1917 publication by the Bolsheviks of the secret May 1916 Sykes-Picot Agreement between Britain and France. 
The Balfour Declaration was a public statement issued by the British government during World War I announcing support for the establishment of a "national home for the Jewish people" in Palestine, then an Ottoman region with a minority Jewish population.
