The third Aliyah refers to the third wave of the Jewish immigration to Israel from Europe who came inspired by Zionist motives between the years 1919 and 1923 (from the end of World War I until the start of the economic crisis in the country). A symbol of the start of the third immigration wave is the arrival of the boat "Roselan" in the Jaffa Port on December 19, 1919. The boat had 650 new immigrants and other returning inhabitants on board. During that period about 35,000 new immigrants[1], arrived in Israel mainly from Eastern European countries - from those about 45% of the immigrants arrived from Russia, 31% from Poland, 5% from Romania and only three percent from Lithuania. Most prominent in this immigration wave is the element of the young pioneers who arrived in the country between the years 1919 until 1921, and after those years their numbers became less amongst the immigrants. The importance of those pioneers was just as great as that of the pioneers of the second immigration wave. Their ideology contributed a great deal to the construction of the country and so they imprinted their mark on Zionism and also on the development of the Jewish settlements in the country of Israel.
In conclusion, the immigrants did have high hopes to the new future in the Holy Land, but even more than that, they were pushed to immigrate due to the developments in Europe and the growth of the nationalism aspirations of various minority groups.
The official Zionist institutions were opposed to the third immigration wave - they feared that the country would not be able to absorb such a great number of people. They even requested that only the people who have enough economic resources would come to the country. But the harsh reality changed their expectations - the bad economic situation of Jews of Eastern Europe and also the riots, forced many to emigrate to countries which did open their gates - United States, Western Europe, and to those who had a pioneering impulse and a Zionist recognition - Israel was suitable as their new home.
Few of the new immigrants (about 1/6) were affiliated with the Yishuv movements of HeHalutz and Hashomer Hatzair. Although most of the new immigrants came from urban backgrounds, and were not affiliated with the major movements, they did align themselves with Zionist ideals.
