Between 1904 and 1914, 35–40,000 Jews immigrated to Ottoman Palestine. The vast majority came from the Russian Empire, in particular from the Pale of Settlement in Eastern Europe. Jews from other countries in Eastern Europe such as Romania and Bulgaria also joined. Jewish emigration from Eastern Europe was largely due to pogroms and outbreaks of anti-Semitism there. However, Mountain Jews from the Caucasus and Jews from other countries including Yemen, Iran, and Argentina also arrived at this time. The Eastern European Jewish immigrants of this period, greatly influenced by socialist ideals, established the first kibbutz, Degania Alef, in 1909 and formed self-defense organizations, such as Hashomer, to counter increasing Arab hostility and to help Jews to protect their communities from Arab marauders. Ahuzat Bayit, a new suburb of Jaffa established in 1909, eventually grew to become the city of Tel Aviv. During this period, some of the underpinnings of an independent nation-state arose: Hebrew, the ancient national language, was revived as a spoken language; newspapers and literature written in Hebrew were published; political parties and workers organizations were established. The First World War effectively ended the period of the Second Aliyah.
