Sibling rivalry is a type of rivalry among siblings, blood-related or not. The likelihood of sibling rivalry is more if the siblings are of the same sex[1].

Origin of sibling rivalry

  • Constant comparision of the siblings by parents
  • Competition for time, attention, love and approval of parents
  • Jealousy


  • Sibling rivalry can cause family problems and hurt the children's relationship with their parents.

Famous sibling rivalry instances

  • Cain and Abel from the Bible -- the sibling rivalry resulted in Cain killing Abel
  • Asha Bhosle and Lata Mangeshkar are on friendly terms now, but during the zenith of their careers, they were huge rivals. See Asha_Bhosle#Rivalry_with_Lata_Mangeshkar
