Just out of curiosity, why did those emperors choose the successors they did, then? Is there a common reason behind all their choices?
simpey enough, they made the follow of wanting to create a dynasty- Tiberius it coudl be understood- Aurelisu not so much, as he himself was the product of being th emost skilled man in th eempire, at leas tin the eyes of the former emperor, Antoninus Pius; who himself was a chosen, and not born emperor.
you see, the golden age of the Roman empire (as a distinct entity from the republic) was between the reigns of emperor Nerve, and Aurelius- these emperors all were either adopted thier suceesor, beginnign with Nerva, or were themselves adopted (Aurelius and his predecessos)
no0w what is adoption in this snese- well Nerva was a wise old sod, he saw that the best way to ensure a truelly workign nation was to select the best candidate to run the empire- a military man, with skilled adminiostration skills, and well liked by th elocal populace, and, more importantlly, the local treoops, and sub comanders- takign all his commander sinto account, he, and the other then selected thier successor, and adopted him into the familly, and named him the heir, offically- the final step was ratifacation by the Imperial senate of his legitimacy as emperor, as the sentate still had a nice chunk of power during this time.
