Judging by the cover art of the series, I'd say the rough RL historical equivalent would be 16th-17th century Europe, perhaps even a bit later -- but in the books gunpowder is only just beginning to be used for anything other than fireworks. There seem to be cage-style lobster helmets (Cromwellilan feel), rapier-type swords and a fair bit of poofy sleeves and lace. Then again, the Aiel are half-naked savages with spears who can kick everybody else's ass, so that doesn't really fit in to RL history. Plus, I get the impression that some civs from the "borderlands" use good old-fashioned broadswords. I don't get the impression that there's much full plate, but rather a lot of "post-plate," sort of what you'd expect once firearms got used more often. I think it's a bit of a mish mash, personally.
I'm sure someone in the WoT thread could give a better answer than what I've given.
The Reason it seemeds mashed is because the lack of stable states to impliment standardized weapons, Armor, Tactics, and Command Structure With the Exception of The Tower Gaurd And The Sheanchan, and possibly the queen's gaurd in andor. Never saw any Rapiers and it seems unlikely that there would be any since the raiper was a responce to heavy plate armor, which there is a lack of in The wheel of time do to the lack of funds. Sabre style swords seem to be the most popular, and the Broad/Longsword in second being used by The Tower Gaurd, Children of The Light, Borderlands, And Warders using them. The Slightly curved Longn sword are common in the borderlands, and The Cutlass and Simitar are Popular with The Sheanchan. Also the the reason for pikes being popular is easy, when you have a peasent levy what else do you do with them, They have no skill with swords or bows or axes, so you teach them drill and disipline and show them how to hold a pike.
