Book excerpt: The Jewish attachment to Zion is many centuries old. Although the modern Zionist movement was organized only a little more than a century ago, the roots of the Zionist idea reach back almost 4,000 years, to the day that the biblical patriarch Abraham left his home in Ur of the Chaldees to settle in the promised land The Historical Dictionary of Zionism is an excellent source of information on Zionism, its founders and leaders, its various strands and organizations, major events in its struggle, and its present status. By showing the movement's strengths and weaknesses, it also acts as a corrective to overly idealistic comments by its supporters and the wilder claims of its opponents. A much more realistic understanding is offered in the Introduction, which presents and explains the movement; the Chronology, which shows its historic progression; the Dictionary, which includes numerous entries on crucial persons, organizations and events; and the Bibliography, which points the way to further reading.
