The Empress Theophanu, wife of Otto II and regent for her son Otto III, was by all accounts a woman skilled at maneuvering through the complicated world of Ottonian politics. When she died in 991 CE, around the age of thirty, she had accomplished much: after arriving in Italy from Constantinople in 972 at around the age of twelve, she became Otto II's queen and was crowned empress of the Western Empire. During her lifetime, she was among the wealthiest women in Europe and one of the continent's most powerful people. After her husband's death, she secured the succession of her son, Otto III, and actively ruled as regent, successfully navigating the dangerous political world of the Western Roman Empire. Her activities included building churches, placing her daughters in positions of power in key nunneries, issuing acts as imperator and imperatrix, receiving ambassadors, waging war and negotiating peace—essentially doing everything expected of a male emperor with the exception of personally engaging in battle. Thietmar of Merseburg, writing around 1013, praises her rule as regent, stating that she held the kingdom for her son “in a manly fashion,” clearly intending this as a compliment. And yet, after her death and the premature death of her son a few years later, Theophanu seems to disappear from the historical record. Despite the great number of contemporary sources in which she figured during her lifetime and immediately after her death, including charters and donations, letters, chronicles, and annals, we know almost nothing about her. The few sources that do mention her in the period following her death have little good to say about her. Why did this woman fall into disfavor?
