​This poster was published by the Association of Islamic and Christian Union and called for the Arab nation (Umma in the poster) to strike on Saturday, November 2, 1929 in protest against the Balfour Declaration, which had been published twelve years earlier.

The poster refers to the Balfour Declaration in derogatory language, calling it the “discriminatory promise” and calls on the public to visit the graves of the “martyrs,” referring to the people killed during the suppression of riots by the British earlier that year. 

The poster was published by an organisation, representing both Christians and Muslims, which suggests that the opposition to the Balfour Declaration and the British Mandate crossed religious lines. This is also suggested in the title of the poster which appeals to the “Arab Nation.” The organisations clearly believed that British policy in Palestine discriminated against the Arab population in favour of the Jewish minority.

This poster was printed in 1929, a year that saw months of tension which had reached a climax a couple of months before this poster was printed. There had been violent riots in Jerusalem, Safed, and Hebron, and over 200 Jews had been killed. In the aftermath of the riots, the Shaw Commission of Enquiry had concluded that the main cause was “the Arab feeling of animosity and hostility towards the Jews.”
