Previously we have discussed the connection between the ancient Basques and the ancient Hebrews and Sumerians. In the Torah (and later the Bible), it states that Abraham was from Ur and it is true that what Jews, Arabs and Sumerians share is y-DNA haplogroup J.
Sumer is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley.

Later, the 3rd dynasty of Ur under Ur-Nammu and Shulgi, whose power extended as far as southern Assyria, was the last great “Sumerian renaissance”, but already the region was becoming more Semitic than Sumerian, with the resurgence of the Akkadian speaking Semites in Assyria and elsewhere, and the influx of waves of Semitic Martu (Amorites) who were to found several competing local powers in the south, including Isin, Larsa, Eshnunna and some time later Babylonia. The last of these eventually came to briefly dominate the south of Mesopotamia as the Babylonian Empire, just as the Old Assyrian Empire had already done so in the north from the late 21st century BC. The Sumerian language continued as a sacerdotal language taught in schools in Babylonia and Assyria, much as Latin was used in the Medieval period, for as long as cuneiform was utilized.
