Duchess Louise of Mecklenburg-Strelitz was Queen of Prussia and the wife of King Frederick William III. The couple's happy, though short-lived, marriage produced nine children, including the future monarchs Frederick William IV of Prussia and Wilhelm I, German Emperor.
Her legacy became cemented after her extraordinary 1807 meeting with French Emperor Napoleon I at Tilsit – she met with the emperor to plead unsuccessfully for favorable terms after Prussia's disastrous losses in the Napoleonic Wars. She was already well loved by her subjects, but her meeting with Napoleon led Louise to become revered as "the soul of national virtue".
