There were several times in history when for big players it looks like the end of history, when situation was stable and there weren't any harbingers of change visible, which were imaginable and didn't look like ASB or cheap SF. Example the regional system of the late bronze age circa 1200BC, it looked for those elites just like the end of history. Some decades later this world dissapeared. For Romans during the Principate also it looked like they were living during the end of history. Barbarians were some disorganized tribes outside borders, relations with the Parthians were settled, with some ocasional short wars sometimes. For elites of "englighted Europe" after the Seven Years War it also looked like a world of peace and prosperity, situation was stable, and any changes were somewhere far far away, in North America or in Poland, but who cared. During the Belle Epoque also it seemed like the end of history and all things were stable.
