The Death Eaters are a fictional extremist group from the Harry Potter series, led by the dark wizard Lord Voldemort. They follow a strict belief in blood purity, thinking that only pure-blood wizards should have power over the wizarding world. Because of this, they feel it is their duty to eliminate wizards born to non-magical families to keep their bloodline pure.
The Death Eaters have a symbol called the Dark Mark, which is a skull with a snake coming out of its mouth. This mark is placed on their left arm and can be used by Voldemort to summon them at any time. The mark burns to signal the call of Voldemort. It also helps them recognise each other. To hide their identities, Death Eaters usually wear black hooded robes and masks.
