Beatrix of Mecklenburg

Beatrix of Mecklenburg, also called Beate (1324 – 5 August 1399), was the youngest daughter of Henry II the Lion and Anna of Saxe-Wittenberg. In March 1325 she was betrothed to Jaromar, only son of Prince Wizlaw III of Rügen. Jaromar died that May and Wizlaw in November, ending the princely house of Rügen.

She was instead given to the Poor Clare convent her father had founded at Ribnitz, taking the habit there aged five in 1329. On 20 May 1349, with a papal dispensation for her youth, she was elected abbess, the first princely abbess of Ribnitz.

The convent church was built in her lifetime, and its chronicle praises her piety and charity. She resigned through illness in 1398 and is venerated as a Blessed.
