kar-NOON-toom once hosted a summit intended to solve an imperial succession crisis. It failed—but changed the path to Constantine.
In November 308 an imperial conference met at kar-NOON-toom under the senior authority of dye-oh-KLEE-shun. The meeting attempted to stabilize the Tetrarchic system after renewed power struggles. Its decisions did not prevent civil war, and Constantine eventually emerged as sole emperor in 324.
The precise conference room is unknown; what matters is that kar-NOON-toom was important enough to host the highest politics of the empire.
The conference is historically secure, but archaeology cannot point to one verified meeting room.
The Roman army here was simultaneously a fighting force, employer, customer, construction organization and magnet for civilian settlement.
What looks like one archaeological attraction is really evidence for a city operating at several social levels at once.
One of kar-NOON-toom's strengths is that archaeology can test the attractive story against material evidence—and sometimes force us to tell a better, less convenient story.
For a visitor, the value is causal rather than chronological: this stop explains why a frontier metropolis needed this particular space, system or institution.
