The year 1916 has recently been identified as "a tipping point for the intensification of protests, riots, uprisings and even revolutions." Many of these constituted a challenge to the international pre-war order of empires, and thus collectively represent a global anti-imperial moment, which was the revolutionary counterpart to the later diplomatic attempt to construct a new world order in the so-called Wilsonian moment. Chief among such events was the Easter Rising in Ireland, an occurrence that took on worldwide significance as a challenge to the established order. This is the first collection of specialist studies that aims at interpreting the global significance of the year 1916 in the decline of empires.
