during much of the middle ages, the agricultural situation in europe changed a lot - the heavy plow allowed large population in eastern europe, and the three-field system produced generally larger yields.
but what if these things were made earlier, during middle or late antiquity? the ancient greeks and pheonicians may not really need a heavy plow, but what if this invention spread to roman gaul/britannia and to the germanic/slavic tribes during the beginning of the first century AD, for example? could this cause the many semi-nomads in northern europe to settle down and form fully-sedentary societies earlier?
