In his book "The Sabra: The Creation of the New Jew", Israeli author Oz Almog, who studied the sociological development of the term, wrote that the process in which a local native culture cut off from the diaspora ways of life and influenced by the ecological and cultural environment in Palestine, as well as the ideology of the labor movement which was dominant in the Yishuv, was emerging as early as the 1920s, and that the first glimmers of a new culture appeared around the time of World War I when the children of First Aliyah immigrants were already displaying traditional sabra characteristics. Avshalom Feinberg has been referred to as "the first sabra." The term was in widespread use in the 1930s and 1940s, and it increasingly became a term of prestige as the sabra turned into a cultural hero. At this time, there was now a large number of native-born Jews in the kibbutzim and moshavim and in urban areas, and as a result, sabra culture blossomed. Almog wrote that "as the Sabra archetype and stereotype took shape, the students at the Hebrew gymnasiums, the young people of the kibbutzim and moshavim, and the members of the youth movements and Palmach began developing a consciousness about their cultural uniqueness. They also produced and honed native status symbols and a peculiarly native Israeli style in language, dress, and collective leisure culture". He also claimed that the idea that a new Hebrew nation had arisen was widespread among Tel Aviv youth in the early 1940s.
