At the turn of the 21st century, a post-punk revival developed in British and American alternative and indie rock, which soon started appearing in other countries, as well. The earliest sign of a revival was the emergence of various underground bands in the mid-'90s. However, the first commercially successful bands – the Strokes, Franz Ferdinand, Interpol, Neils Children and Editors – surfaced in the late 1990s to early 2000s, as did several dance-oriented bands such as the Rapture, Radio 4 and LCD Soundsystem. Additionally, some darker post-punk bands began to appear in the indie music scene in the 2010s, including Cold Cave, She Wants Revenge, Eagulls, the Soft Moon, She Past Away and Light Asylum, who were also affiliated with the darkwave revival, as well as A Place to Bury Strangers, who combined early post-punk and shoegaze. These bands tend to draw a fanbase who are a combination of the indie music subculture, older post-punk fans and the current goth subculture. In the 2010s, Savages played a music reminiscent of early British post-punk bands of the late '70s.

Question: Officially, human sacrifice was obnoxious "to the laws of gods and men." The practice was a mark of the "Other", attributed to Rome's traditional enemies such as the Carthaginians and Gauls. Rome banned it on several occasions under extreme penalty. A law passed in 81 BC characterised human sacrifice as murder committed for magical purposes. Pliny saw the ending of human sacrifice conducted by the druids as a positive consequence of the conquest of Gaul and Britain. Despite an empire-wide ban under Hadrian, human sacrifice may have continued covertly in North Africa and elsewhere.
Is there an answer to this question: What ruler banned human sacrifice empire wide?

Answer: Hadrian
