The trend began in the United States of America in the first few decades of the 20th century when "an increasingly large section of Americanized Jewish opinion began to shift away from anti-Zionism (...) either to pro-Zionism or non-Zionism. (...) The non-Zionists were willing to offer the fledgling Jewish homeland fiscal and diplomatic counsel, not for their own benefit or spiritual comfort but for those Jews who chose to reside there."
Difference from anti-Zionists 
"There is a marked difference between non-Zionism and anti-Zionism. A non-Zionist may challenge the theoretical underpinning of the concept of an 'ingathering of the exiles' in an independent Jewish State. If Jewish, he will not choose to live in Israel, nor will he approve of the notion of other Jews living there (...) but anti-Zionists do not find it sufficient to be dissatisfied with a decision made and implemented a long time ago. They are not content with a critical assessment of the situation confined to an historical (and, accordingly, a theoretical) framework. Not merely do they have an adverse opinion about the establishment of Israel in the past, but they contest the legitimacy of Israel as a State in the present time and the future."
Contemporary definitions 
Non-Zionism has also been defined in terms of a non-position on Zionism. For example, Anthony Frosh on online Jewish magazine Galus Australis, has defined a non-Zionist Jews as a Jew "who does not have any particular political relationship (positive or negative) with the State of Israel, or at least little more of a relationship than they would have with some other 3rd party state."
Haredi Non-Zionism 
Generally, those groups of Ashkenazi (Western) Haredi Jews who participate in the Israeli government but do not believe in the religious ideology of Zionism are known as "non-Zionists". The most prominent non-Zionist Haredi group is Agudath Israel. This is in contrast to the religious Zionist Mizrachi party (which believes the State of Israel to be the beginning of the redemption); and also in contrast to the anti-Zionist Haredi groups, such as Satmar and the Edah Charedis that op.enly oppose Zionism and have little to no interaction with the State of Israel, and no representation in government. Unlike the older definition, many live in the State of Israel. They tend to be extremely pro-Israel politically, as can be seen in such publications as Mishpacha and Hamodia. Sephardi Haredi Jews may refer to themselves as Zionist.
