Jera stems from Proto Germanic jēra, Proto Norse jāra and Old English ġēr and means as much as “harvest, season and good year”.

The English word “year” stems from this word that has its PIE root in “yer-o”. It’s associated to prosperity, wealth and the bounty of a blissful harvest.

The Germanic people lived off the land and it wasn’t until the Neolithic Revolution, when western hunter-gatherers and Neolithic farmers met, that farming became established in western Europe. Farming meant a growth of population, often of wealth and the rise of the first villages and cities that became European civilization.

To sow and to harvest is a cycle and the harvest of crops also meant survival during icy winters. Indo-European cultures were farming-cultures and the role of Agriculture is extremely important in order to understand how the cultures and populations of Europe developed over a long period amount of time.
