Why is "Armour in the 18th century" trending?

Wikipedia Overview

Armour in the 18th century was minimalist and restricted almost entirely to cavalry, primarily to cuirassiers and, to a lesser degree, carabiniers and dragoons. Armour had been in rapid decline since the Thirty Years' War, although some archaisms had lingered on into the early years of the 18th century, like Austrian cuirassiers with buff coats and lobster-tailed helmets or Hungarian warriors with mail armour and shields. With the exception of Poland-Lithuania, which still made use of hussars wearing suits of plate armour, armour in Europe was primarily restricted to a breast- and backplate, the cuirass, and a simple iron skull cap worn under the hat. By the later 18th century, there were two contradicting developments. Many cuirassier regiments were discarding their cuirasses, while helmets in the form of so-called dragoon helmets, made of brass or leather, made a comeback among the cavalry and infantry.
