Why is "Cultural depictions of Frederick I, Holy Roman Emperor" trending?

Wikipedia Overview

Frederick I, nicknamed Barbarossa, was one of the most notable Holy Roman emperors, who left a considerable political and cultural legacy, especially in Germany and Italy. Thus, he has been the subjects of many studies as well as works of art. Due to his popularity and notoriety, in the 19th and early 20th centuries, he was instrumentalized as a political symbol by many movements and regimes: the Risorgimento, the Wilhelmine government in Germany, and the National Socialist movement. Today, when a tradition-establishing form of commemoration for the emperor is no longer necessary, scholars like Kurt Görich call for neutrality and warn against the instrumentalization of the historical person in the other way. Modern historians generally reject nationalist myths, while portraying the emperor as an influential ruler who suffered many setbacks but often managed to recover. He reestablished in Germany, enhanced the imperial position, but also made mistakes when trying to assert his authority over North Italian communes, leading to a prolonged struggle. After being humbled in the Battle of Legnano, he changed his policies and attained a better working relationship with the Italian communes. His successful diplomatic efforts together with a developing circumstance also opened new possibilities for the imperial position, notably through the marriage of his son Henry VI with Constance of Sicily. Different studies explore different aspects of his personality, with recent German scholarship emphasizing the emperor's relationship with the chivalrous-courtly culture of the time.
