 The nearly five years of rule by the so-called Islamic State, inflicted on millions of citizens in Iraq and Syria, will be remembered for its extreme brutality. It targeted Christians, Shia Muslims, ethnic Yazidis, policemen and their families, anyone in fact who opposed its narrow and violent version of Sharia, Islamic law. The group lost the last of its physical territory in 2019, but it has since shifted its focus to sub-Saharan Africa.
