Human prehistory is rich with wandering peoples. Over thirteen thousand years ago the first Americans were walking over the land bridge with their stuff in tow. Of course they did not call themselves Americans. Back then people moved themselves. No moving company needed.
With the invention of the wheel folks could make carts and that made moving a little easier. But still folks moved them self. Only kings and the super rich had enough stuff to need movers, but they had slaves and subjects to do the heavy lifting for them.
It is interesting to note that when humans were hunters and gathers and moving around the most, they had the least amount of stuff. Packing up the whole tribe was no big deal. Down came the tents and they were off to follow the migration patterns of their prey.
Planet earth was colonized this way. Year by year. Generation by generation. Little by little soon there were humans on six out of seven continents. And that is not bad for walkers with backpacks.
As the agriculture revolution took hold people moved less. staying close to their crops, and the upcoming harvest. Young men and women would get married and start a life together and move to a place of their own. Normally still close by the tribe, and the mother in law. The ???local move” was born. But just like many newlyweds today, they just did not have enough stuff to hire a moving company. They were D.I.Y.ers.
During the great conquests of the ancient empires the winning army would often carry their loot back to their capitals. But back then the military was not yet out sourcing to moving companies. The army took care of it themselves. Probably for the better because professional moving companies do not move slaves and livestock, and also recommend you move your old coins, jewelry and gold yourself.
The DIY movers have a proud tradition dating back to time immemorial. For most of human history folks moved themselves. Now they can rent a moving truck and DIY in style. Or hire a moving company and enjoy the ease of a professional move.
