Of course Harry Potter was probably the most important Wizard of these few years. When the Dark Lord(Voldemort) was in his first years, James Potter and Lily Potter(his parents) were killed. However, his mother, Lily protected Harry with love. Therefore, when Voldemort tried to kill Harry, it left a scar shaped like a lightning bolt on hi forehead. He Who Must Not Be Named was temporarily desroyed and went into one of his Horcruxes(see Notable objects for more information). When James and Lily Potter were killed, Proffesor Albus Dumbledore and Proffesor Minerva Mcgonagall brought baby Harry to The Dursleys to adobt Harry.
