I am interested at this and not sure whether they appeared in 15 or 16 century.

So who designed them?

halberd is hard to define as to when they appeared. the term halberd has been around for quite a while, Nigel's saga defines one of the hero's primary weapon as halberd - some kind of spear in its use but the term halberd i think means something like staff axe.

its such a diverse weapon that seems to have been adopted by most European cultures that i don't think you can attribute just one culture with the development of them - moreover each culture seems to have made their own style.

i can just tell, that, that design is 16th century onwards, that design started to appear around the time halberds became symols of rank and office more than being front line weapons, although make no mistake it would still hurt
I am pretty certain that is 16th century, probably the second half of the century i would guess.

Its a pretty standard late 16th to mid 17th cent pattern.

There is a soldier carrying one on this re-enactment article, scroll down the page to find him

He's in one of the London Trained Bands and the pic is approx 1580's

I wouldn't use it much earlier than that, but they do a nice swiss style one here which is great for 15th cent plus a wee bit earlier and later.

As was stated above, that's a pretty standard type of halberd. Here's a very similar one I photographed at the Higgins Armory recently.

If you're truly interested in the history of halberds, you will likely want to seek a copy of the book Hafted Weapons of Medieval and Renaissance Europe: The evolution of European staff weapons between 1200 and 1650, by John Waldman (2005). Waldman spends a lot of time covering the development and construction of the halberd, starting with the bardiche and proceeding through many forms of this weapon type.

If you can't get ahold of this book, try your nearest university. If it's not in the catalog, it's probably something they can borrow from somewhere else; possibly even an electronic copy.

thank you for telling me such a book, I doubt university in Malaysia would have it. So my best option is order it online

I didn't mention that I agree with previous posters that the top halberd on the link you posted is likely late 16thC or 17C according to information in Waldman's book. I was distracted by the other halberds present on the page, but I assume you are interested in the top one.

The item listed here:

http://www.lutel-handicraft.com/?p=productsMo...berd-20017

...is late XIVth century inspired. I have a copy of it. Well built piece. Comes unhafted; socket has 1 3/8" (~3.49cm) inner diameter. They send modern wood screws for mounting (blackened), so you would want to find some iron nails if you want a more period mount.

Lutel is also Czeck. Item listed for 175 Euro or $240.
