In the early 20th century, the term "Southern Syria" was a slogan that implied support for a
Greater Syria nationalism associated with the
kingdom promised to the
Hashemite dynasty of the
Hejaz by the British during World War I. After the war, the
Hashemite prince
Faisal attempted to establish Pan-Levantine state —a united kingdom that would comprise all of what eventually became
Syria,
Lebanon,
Israel,
Jordan, and
Palestine, but he was stymied by conflicting promises made by the British to different parties (see
Sykes–Picot Agreement), leading to the
French creation of the
mandate of Syria and Lebanon in 1920. One of the resolutions adopted at the first
Palestinian Arab Congress in 1919, Jerusalem, was: "We consider Palestine nothing but part of Arab Syria, and it has never been separated from it at any stage. We are tied to it by national, religious, linguistic, moral, economic, and geographic bounds." Yoav Gelber notes that the Historians of
Palestinian Nationalism such as
Yehoshua Porath and Muhammad Y. Muslih consider the declaration to have been ideologically disingenuous, pointing out that there was a split among Palestinians regarding the resolutions' implications. The younger generation was eager to pursue political opportunities in a unified Levantine state under
Faisal I, and the older generation wished for Palestine's Independence to maintain their autonomous power in the post-Ottoman world order. Nonetheless, the resolution was mainly supported in the hopes of thwarting support for the
Jewish National Homeland that was introduced in the
1917 Balfour Declaration on the occasion of the upcoming
San Remo Conference by presenting that Palestine already belongs to another
nation than
Jews. The notables in Faisal's government in Damascus, such as Iraqis and Damascenes, including the Palestinians, had some conflict, and each sought to place their interests above others. In 1932, a Palestinian Arab party named whose name "Hizb Al-Istiqlal" (
Independence Party ) was established in
Mandatory Palestine by the
Sorbonne educated lawyer
Awni Abd al-Hadi, whom Daniel Pipes says it the reaffirmed support for the incorporation of Palestine and its people into a Pan-Levantine state. After when Mandatory Palestine ceased to exist in the aftermath of the Palestine War: the term has been used by Syrian Baathists who sought to expand Syria's borders and justify aggression against Israel, such as Hafiz Al Assad in 1974. The Baathists later went on to create Baathist Palestinian groups such as Al-Saqia in an effort to dominate the
PLO and wrest it from
Fatah. As of the 1990s
Israeli-Syrian peace process, and the
Syrian Civil War in the early 2010s: the Baathist party of Syria stopped claiming
Israel and the
Palestinian territories as "Southern Syria". ==References==
