Then Voldemort killed Lily the contract was broken and the person Lily died for Harry did get protection from Voldemort . In the battle of Hogwarts Voldemort again created such a contract then he asked that if Harry sacrificed himself nobody else would be killed and then Voldemort killed Harry the contract was sealed and Voldemort and his death eaters could no longer hurt those Harry died for and was soon afterwards defeated .
