Draco Malfoy's gang was a group of Slytherins who were often the children of Death Eaters, and/or Voldemort sympathisers. Most of them hung around Draco Malfoy, the son of a well-known Death Eater and wealthy pure-blood, Lucius Malfoy. Most of the members were known pure-bloods, using their status in order to assert their dominance as wizards. At least Crabbe and Gregory's fathers were known Death Eaters as well.That may be the reason they knew each other so well, seeing as Draco made friends with them shortly after meeting in their first year at Hogwarts.
The gang generally used their abilities and statuses to bully and terrorise the other students of different houses at Hogwarts, especially the younger students. Draco and his gang frequently antagonised Harry Potter and his friends, and Malfoy also used his position as prefect to bully some first years when he got the power in his fifth year. Their main target of hatred were Muggle-borns and Blood traitors alike.
