Dear group;
OK, here we go. First, the type of helmet which is generally classified as a *Conquistadore Helmet* is in fact correctly known as the Morion helmet. Some historians think that it may have been first influenced by the Moors, hence the name Morion, however there is no hard proof to support this proposition.
The earliest known Morions to be worn were issued to British and Irish foot soldiers in the early 15th century and became popularized by the Spanish conquistadores soon thereafter. The reason for it's evolvement reflects heavily on the battlefields changes which were introduced soon after the first rifles appeared on the field.
Around the same time that the morion was seeing action on the battlefields of Europe, changes in metal manufacturing were also taking place and Morion helmet reflected these shifts in technology. The Morion helmet was lighter in comparison to previous designs, with the raised central comb providing additional strength without adding a lot to the overall weight.
In fact, the entire design of the Morion helmet aptly reflects the engineering achievements of the period. The severe slope of the brim and beaver were deigned to provide lateral stiffness from blows aimed at the sides, and with a slight tilt of the head towards the shoulder, provided needed neck protection from missile weapons of the day.
Because the Morion design helmet was so cost effective to produce and could be manufactured in large numbers, it was therefore issued to large numbers of foot soldiers throughout Europe until at least as late as WWI, surviving as the Adrian helmet, worn by the French infantry.
Since all early Conquistadores had either previously served in the Spanish military or were severely short on funds, the Morion provided a cost effective alternative to the much more expensive and wieldier full face helmets of the preceeding age, therefore it made practical financial sense to wear the Morion helmet along with a light steel cuirass.
Since so many Conquistadores thought that having ones' portrait painted gave them an air of noblility, they were therefore portrayed over and over wearing their Morion helmets and cuirasses. This is why the Morion became an inseparable part of Conquistadore lore.
