Planning to work on a new TL, entitled Belisarius, Emperor which features Flavius Belisarius, Justinian's general, becoming Eastern Roman Emperor. POD is in 535 AD. Butterflies include no Plague of Justinian, a militarily stronger and larger ERE, and so forth.

So, my question is: what is the most plausible way to have Belisarius become Emperor? If I can just figure out how to achieve this, everything will fall into place.

Thanks in advance!
