These figures have been supported by later studies[34], though estimates of Arab immigration have been disputed.[35] Initially, Jewish immigration to Palestine met little opposition from the Palestinian Arabs. However, as anti-Semitism grew in Europe during the late 19th and early 20th centuries, Jewish immigration (mostly from Europe) to Palestine began to increase markedly, creating much Arab resentment. The British government placed limitations on Jewish immigration to Palestine. These quotas were controversial, particularly in the latter years of British rule, and both Arabs and Jews disliked the policy, each side for its own reasons. In response to numerous Arab attacks on Jewish communities, the Haganah, a Jewish paramilitary organization, was formed on June 15, 1920 to defend Jewish residents. Tensions led to widespread violent disturbances on several occasions, notably in 1921, 1929 (primarily violent attacks by Arabs on Jews — see Hebron) and 1936–1939. Beginning in 1936, several Jewish groups such as Etzel (Irgun) and Lehi (Stern Gang) conducted their own campaigns of violence against British military and Arab targets. This prompted the British government to label them both as terrorist organizationsen.wikipedia.org
