The Romans had a simple method of romanizing new provinces:

The conquered them in battle, bribed local elites and lured their youth with the comforts of Roman civilization and career opportunities, then after 20-30 years they destroyed the last hope for freedom by crushing a general uprising in force.


In Parthia they failed with the conquering part, in Germany they failed with the 'crush the general insurrection' part.

They weren't exactly good at pacifying within a decade.


Hmm, maybe every village should have been asked send one or two bright youth to a U.S. University and be handed a cheap laptop with webcam and mobile phone connection?
