The New Historians (ההיסטוריונים החדשים, HaHistoryonim HaChadashim) are a loosely defined group of Israeli historians who have challenged traditional versions of Israeli history, including Israel's role in the 1948 Palestinian exodus and Arab willingness to discuss peace. The term was coined in 1988 by Benny Morris, one of the leading New Historians. According to Ethan Bronner of The New York Times, the New Historians have sought to advance the peace process in the region. Much of the primary source material used by the group comes from Israeli government papers that were newly available as a result of being declassified thirty years after the founding of Israel. The perception of a new historiographical current emerged with the publications of four scholars in the 1980s: Benny Morris, Ilan Pappé, Avi Shlaim and Simha Flapan. Subsequently, many other historians and historical sociologists, among them Tom Segev, Hillel Cohen, Baruch Kimmerling, Joel Migdal, Idith Zertal and Shlomo Sand have been identified with the movement. Initially dismissed by the public, the New Historians eventually gained legitimacy in Israel in the 1990s. Some of their conclusions have been incorporated into the political ideology of post-Zionists. Avi Shlaim described the New Historians' differences from what he termed the "official history" in the following terms: The official version said that Britain tried to prevent the establishment of a Jewish state; the New Historians claimed that it tried to prevent the establishment of a Palestinian state The official version said that the Palestinians fled their homes of their own free will; the New Historians said that the refugees were chased out or expelled The official version said that the balance of power was in favour of the Arabs; the New Historians said that Israel had the advantage both in manpower and in arms The official version said that the Arabs had a coordinated plan to destroy Israel; the New Historians said that the Arabs were divided The official version said that Arab intransigence prevented peace; the New Historians said that Israel is primarily to blame for the "dead end".
