And then you see the land that is cultivated collectively by this community, not just the actors that we've just talked about. You might also have a church or a monastery on that manor right over here. And these strips of land, they might have different crops and the output of those crops go to different people. The one common factor is the lord of the manor might get all of the crops from some of these strips, while on the other strips, they get the taxation, so they'll get a certain percentage from the crops there. But all of the work is done by the serfs and the free peasants, and possibly, if this is a monastery and there are some monks at the monastery. Now, one interesting thing is why you often see in these manor maps these long strips of land. And our resident agricultural expert at Khan Academy, David Reinstrom, says it's because the medieval plows, once you got going, you didn't wanna turn them around.
