Not all agricultural societies become civilizations, but no civilization can become one without passing through the stage of agriculture. This is because at some stage in the development of agriculture, as productivity improves, not all people would need to be engaged in producing or procuring food. A significant number of people could be freed up to pursue other activities such as building walls or monuments for new cities, making new tools, weapons and jewellery, organizing long-distance trade, creating new artistic masterpieces, coming up with new inventions, keeping accounts, and perhaps constructing new public infrastructure such as irrigation canals that further improve the productivity of agriculture, thus realizing even more people to do new things. This can happen, of course, only if a society that has transitioned to high-productivity agriculture has also, at some stage in its evolution, found a way to channel the bonanza of free time into other work fruitfully. In the ancient world, this often involved creating new ideologies and new hierarchies or power structures to coerce or otherwise convince large groups of people to devote their time to the new tasks for very little reward.
