Palestine, Eretz-Israel, Israel, Terra Santa, The Holy Land, Philistines—all those names have been given to a stretch of land situated on the eastern shore of the Mediterranean Sea. This was, and still is, one of the most important pieces of land, which the world has been dealing with during the last two thousand years. The Arab-Israeli conflict, which has run for the last hundred years, is but the last in a series of long struggles, which dictate the history of that area. One of the main issues is the delimitation of Palestine, a process that began about 100 years ago but is far from complete. Understanding this process is the aim of this essay, which will present an historical review and an analytical view concerning the actors involved in the process and an overview dealing with the three eras of boundary making of Israel.
