Saint Mathilda (or Matilda, – 14 March 968) was the wife of King Henry I of Germany, the first ruler of the Saxon Ottonian (or Liudolfing) dynasty, thereby Duchess (consort) of Saxony from 912 and Queen (consort) of Germany (East Francia) from 919 until her husband's death in 936. Their eldest son Otto succeeded his father as King of Germany (East Francia) and years later was crowned Holy Roman Emperor in 962, thus ending the vacancy of this office begun in 924 with the death of Holy Roman Emperor Berengar I of Italy. Matilda lived to see the imperial crown restored under her son. Matilda's surname refers to Ringelheim, where her comital (of or relating to a count or earl) Immedinger relatives established a convent about 940.
