The wave of initial revolutions and protests faded by mid-2012, as many Arab Spring demonstrations met with violent responses from authorities, as well as from pro-government militias, counter-demonstrators, and militaries. These attacks were answered with violence from protesters in some cases. Large-scale conflicts resulted: the Syrian Civil War; the rise of ISIL, insurgency in Iraq and the following civil war; the Egyptian Crisis, coup, and subsequent unrest and insurgency; the Libyan Civil War; and the Yemeni Crisis and following civil war. Regimes that lacked major oil wealth and hereditary succession arrangements were more likely to undergo regime change.
