Why Knight's Armor Developed Only In Europe

Become a Call of History member:    / @call_of_history   In 476 AD, Rome fell. A barbarian named Odoacer deposed the last Western Roman Emperor, Romulus Augustus, and established his own barbarian kingdom in Italy. Thus ended the era of antiquity. For the next 300 years, Europe plunged into darkness. But soon, on the battlefields where legionaries once dominated, a new class of warriors emerged - the knights. Mounted warriors whose main symbol became the full plate armor. But did knights really wear such armor for most of history? It might surprise some of you, but full plate armor appeared in Europe even after the advent of the first firearms! For example, in the Battle of Crécy, which occurred in the early stages of the Hundred Years' War, cannons were already in use, but none of the knights wore full plate armor. So, what kind of armor should really be associated with knights? Why did full plate armor only emerge in Europe? And why didn't even the Romans, who had the means, armor their legionaries in plate?
