Gero I (c. 900 – 20 May 965), sometimes called the Great (Latin: magnus),[1] was a German nobleman who ruled an initially modest march centred on Merseburg in the south of the present German state of Saxony-Anhalt, which he expanded into a vast territory named after him: the marca Geronis.[2][3] During the mid-10th century, he was the leader of the Saxon Ostsiedlung.
