The Jews' State (Der Judenstaat) is considered one of the most important texts of early Zionism. As expressed in this book, Herzl envisioned the founding of a future independent Jewish state during the 20th century. According to Herzl after centuries of various restrictions, hostilities and frequent pogroms, the Jews of Europe have been reduced to living in ghettos. The higher class is forced to deal with angry mobs and so experiences a great deal of discomfort; the lower class lives in despair. Middle-class professionals are distrusted, and the statement "don't buy from Jews" causes much anxiety among Jewish people. It is reasonable to assume that the Jews will not be left in peace. Neither a change in the feelings of non-Jews nor a movement to merge into the surrounds of Europe offers much hope to the Jewish people. Herzl argued that the best way to avoid anti-semitism in Europe was to create an independent Jewish state. The book encouraged Jews to purchase land in Palestine, although the possibility of a Jewish state in Argentina is also considered.
