Adelaide was born to King Rudolph II of Upper Burgundy (now Switzerland) and Bertha of Swabia. Her parents became king and queen of (northern) Italy after the death of Berengar I. Later, after her father's death, Adelaide was married to the new King of Italy, Lothair II. She was 15 years old. They had a daughter, Emma of Italy, who married King Lothair of France.
After Lothair died, his successor Berengar II tried to force a marriage between Adelaide and Berengar's son, Adalbert. Adelaide refused and fled, but was caught and imprisoned for four months. She managed to escape and (we believe) found while in hiding by a priest who took her to a safe refuge. From there she wrote to Otto I asking for protection. They met and married on 23 September 951. (See the two at Meissen Cathedral in the illustration.)
Otto had been married before, but when his son Liudolf, Duke of Swabia, led a revolt that was quelled, Otto dispossessed Liudolf of his title. This was a good sign for any future children of Otto's and Adelaide's. They had a couple sons who died while young, but they continued producing children, including Otto II.
Otto I was crowned Holy Roman Emperor on 2 February 962 by Pope John XII, whom Otto (accompanied by Adelaide) had come to Rome with an army to protect against John's enemies. In a first for the Holy Roman Empire, John crowned Adelaide as Holy Roman Empress.
Adelaide's influence in the Empire was significant. She was named alongside Otto in papal bulls. She was involved in 75 charters. She received requests for help and protection separate from her husband. Her daughter Emma wrote, asking for help against enemies, as did future Pope Sylvester II, Gerbert of Aurillac.
After a later expedition to Rome to support Pope John XIII, Adelaide remained in Rome with her son Otto for six years. In 967, Otto II was crowned co-emperor, and in April 972 Otto married Theophanu, daughter of a former Byzantine Emperor. When Otto I died in 973 and Otto II became Holy Roman Emperor in his own right, Adelaide did not relinquish any of the authority she was accustomed to wield, which interfered with her son's run and clashed with her daughter-in-law.
Tomorrow we'll go back to Theophanu and see how things were between her and her mother-in-law.
