Why is "Bohemian Revolt" trending?

Wikipedia Overview

The Bohemian Revolt was an uprising of the Bohemian estates against the rule of the Habsburg dynasty that began the Thirty Years' War. It was caused by both religious and power disputes. The estates were almost entirely Protestant, mostly Utraquist Hussite but there was also a substantial German population that endorsed Lutheranism. The dispute culminated after several battles in the final Battle of White Mountain, where the estates suffered a decisive defeat. This started re-Catholisation of the Czech lands, but also expanded the scope of the Thirty Years' War by drawing Denmark and Sweden into it. The conflict spread to the rest of Europe and devastated vast areas of Central Europe, including the Czech lands, which were particularly stricken by its violent atrocities.
