Point number 12 in the history of Gedera as depicted on the wall at the southern entrance of the town.
This is actually the second wave of the emigration of Yemeni Jews. The first wave occurred in 1881-1882 (the rise of "Aale Batamar"). The emigration that the sign speaks of is the "Yavneeli emigration", which happened in the plan of Arthur Ruppin’s plan to replace the local (Arab) workers who worked in the colonies with Yemeni immigrants.
