Excerpt:
The complete map presents the development of Jewish settlement over three periods, and the green shading indicates the expansion of Jewish owned land
The Zionist Organization, established at the First Zionist Congress in Basel in 1897, the Palestine Office and its successor the Jewish Agency, Keren Hayesod, which coordinated the collection of donations for the development of the country, and the Jewish National Fund, all assisted over the years in purchasing land and establishing Jewish settlements in the Land of Israel. In this map, summarizing the work of these bodies between 1897 and 1947, the editor chose to highlight the sites that in his view constituted milestones in the timeline of settlement of the Land of Israel.
For example, “Degania 1909 ‘The Mother of Kvuzot’” – Degania was the first Jewish communal settlement to be established in the Land of Israel.
