Looking through the logs, I see that someone from France found my blog by Googling "gaza arab government 1948." They found this post from December 2005 which unfortunately had lost all its graphics. I just restored them, and the article shows yet again that there is nothing new under the sun.
In brief: in 1948, the ex-Mufti of Jerusalem set up his own government in Gaza, complete with a flag. It was recognized by Egypt, Syria, Saudi Arabia, Iraq and Yemen.
When Israel counterattacked Egypt in late 1948, half the cabinet resigned and all of them bravely fled to Cairo.
It was such a spectacular failure that no Palestinian Arab mentions this original and only "Palestinian state" today out of embarrassment.
