After a large war with high civilian/peasant casualties, I’d assume that agriculture would be disrupted. In order to get more people back in the fields, would it be feasible for people living in city slums to be offered farming land if they were willing to relocate to it? They’d lack the knowledge required for farming, but, realistically, could that be taught to them in large numbers? If so, would the lords of cities filled with the poor consent to it, glad to get rid of them?
