In 1955, G. Ernest Wright discussed the correlation of archaeological data to the early Israelite campaigns, which he divided into three phases per the Book of Joshua. He pointed to two sets of archaeological findings that "seem to suggest that the biblical account is in general correct regarding the nature of the late thirteenth and twelfth-eleventh centuries in the country" (i.e., "a period of tremendous violence").[30] He gives particular weight to what were then recent digs at Hazor by Yigael Yadin.[30]
