<p>Not in particular. Tolkien was very creative and didn't base too much from real life cultures. So mostly mod-made factions like Morwaith and Taurethrim. Tbh both Morwaith and Taurethrim look like some cheap Indiana Jones adventure moviw rip-off Aztec and Zulu. Haradrim also look a lot like Northern Africans/Arabians with Umbar and Coast Southron being like Carthage/Saracens, Corsairs being Berber pirates, and harnedor being Bedouin. Only Gulfings are weird, warrior culture with ziggurats. Gondor I thougt to be like Medieval Europe, but it's actually more like later age Byzantines at the time of the War of the Ring. Although it has much different culture than both </p>
