The Conquerors event is triggered when an Old World Civ (not necessarily European) meets a New World Civ in a certain area which is near the New World Civ's spawn. It is only triggered the first time this happens. The contact must occur between ten turns after the Aztec spawn (1300AD) and 1800AD. The Old World Civ will then get a variable number of Conqueror units next to the New World Civ's spawn tile depending of several factors. They will also DoW on the New World Civ if the the Old World Civ is an AI.
Thanks for the info (If you don't mind, I might put that into a wiki article...).
I'd tried for one in the mid 1100's just after Inca spawned, but to no avail. Anyway, it worked later on. It's neat having a Japanese Mexico....
