As with many things in history, it’s highly disputed when and where windmills were invented. What the evidence does show however, is that the Persians built so-called panemone windmills around the 5th and 6th century.
Due to the very windy conditions, these vertical windmills were very popular in the region which now is the Iranian-Afghan border. The inventor is unknown, although documents reveal that during the sixth century, a Neo-Persian soldier by the name of Piruz Nahavandi was skilled in the art of creating windmills. Despite not being the most efficient type of windmill, panemone windmills are still being used in many parts of the World.
