Modern Jewish immigration and colonization of Palestine started in the eighth decade of the 19th century. Though it took some time until the Arabs started to formulate their opposition towards these activities. At the turn of the century, with the formulation of the Zionist political programme, some Arabs started to voice their opposition in various forms. They were increasingly well informed about Zionist goals and aware of the implications of their policies. However several structural barriers prevented anti-Zionism from becoming a broader movement.
