The outrageous violence of Bloody Week became a rallying cry for the working classes ; politicians would later proudly brag about their participation with the Commune.

Bloody Sunday was followed, nationwide, by workers ’ and students ’ strikes, street demonstrations, spates of vandalism and other periodic violence, assassinations of government officials, naval mutinies, nationalist movements in the imperial borderlands, and anti-Jewish pogroms and other reactionary protest and violence.

Famous rock musicians have adopted causes ranging from the environment ( Marvin Gaye's " Mercy Mercy Me ( The Ecology )") and the Anti-Apartheid Movement ( Peter Gabriel's " Biko "), to violence in Northern Ireland ( U2's " Sunday Bloody Sunday ") and worldwide economic policy ( The Dead Kennedys ' " Kill the Poor ").

The Bloody Sunday Inquiry, also known as the Saville Inquiry or the Saville Report after its chairman, Lord Saville of Newdigate, was established in 1998 by British Prime Minister Tony Blair after campaigns for a second inquiry by families of those killed and injured in Derry on Bloody Sunday during the peak of ethno-political violence known as The Troubles.

This second criticism was also echoed in comments from Protestants reported in The Belfast Telegraph that the report created an unjust hierarchy in which the victims of Bloody Sunday were unfairly elevated above the more numerous victims of IRA violence.
