The Motrice Pia was an early three-wheeled vehicle, introduced by Italian Enrico Bernardi, and sometimes credited as the first motorcycle.[1] The exact year of introduction depends on which one of the following milestones one considers: the demonstration of a gasoline engine in 1882–1884 (first used to power a sewing machine),[2][3] the application of the engine to a child's tricycle in 1884,[4] the application of this engine to a motorized tricycle (or low cart) in 1893,[2][5] or the mounting of the motor behind a bicycle on a one-wheel trailer via chain drive creating a "motorcycle" in 1894.[2]

Daylamites

Map showing Daylam in western Tabaristan. The Daylamites or Dailamites (Middle Persian: Daylamīgān ; Persian: دیلمیان ‎ Deylamiyān ) were an Iranian people inhabiting the Daylam—the mountainous regions of northern Iran on the southern shore of the Caspian Sea. [1] They were employed as soldiers from the time of the Sasanian Empire, and long resisted the Muslim conquest of Persia and subsequent Islamization. In the 930s, the Daylamite Buyid dynasty emerged and managed to gain control over much of modern-day Iran, which it held until the coming of the Seljuq Turks in the mid-11th century.
