The 'Year of Catastrophe' and the birth of modern territorial conflict
In short: In 1920, a collapse of diplomatic promises transformed Palestine into a flashpoint of competing nationalisms. As Great Britain transitioned from military to civilian rule, the region became a laboratory for conflicting visions of sovereignty—where one group’s promised independence was another's existential threat.
The roots of the intercommunal conflict lie in contradictory wartime promises made by Great Britain during World War I. While the Hussein-McMahon correspondence (1915–1916) suggested independence for Arabs in exchange for support against the Ottomans, the secret Sykes-Picot Agreement (May 1916) planned to internationalize the bulk of Palestine. The Balfour Declaration, issued during November 1917, added layers to this uncertainty by stating British support for a Jewish homeland while also claiming to safeguard the religious and civil liberties of local non-Jewish populations.
The geopolitical shift solidified in April 1920 at the San Remo Conference, where the Allies mandated Palestine to Great Britain. This effectively collapsed Arab hopes for a federated Syrian state under Faisal I, leading Palestinian Arabs to label 1920 as 'ʿām al-nakbah,' or the 'year of the catastrophe.' The transition to civilian rule in July 1920 saw the appointment of Sir Herbert Samuel, a Zionist, who began implementing quotas for Jewish immigration—specifically 16,500 for the first year—which immediately stoked tensions with the Arab Executive established in Haifa.
These tensions manifested in violent riots as early as April 1920 in Jerusalem and May 1921 in Jaffa. The conflict was fueled by both British policy and deep-seated fears: Arabs feared a massive influx of Jews and the eviction of peasants (fellahin) for land purchases by the Jewish National Fund, while early Zionist leaders often operated under the self-persuasive belief that Arabs would eventually assimilate into a Jewish-led society. By 1922, Britain was forced to issue a white paper attempting to balance these irreconcilable claims by stating Palestine would not be converted entirely into a Jewish home.
Ultimately, the period established a pattern of shifting from sectarian clashes in the 1920s to organized armed revolts in the 1930s and 40s. It highlights how colonial administration can entrench conflict when it attempts to fulfill mutually exclusive promises to different populations simultaneously.
