What year was the horse carriage invented?

The horse carriage wasn't invented in a single year, but rather evolved over a long period.

* Early forms of horse-drawn transport: The earliest forms, like sleds and carts, date back to around 4000 BCE.

* Chariots: These were developed around 2000 BCE and were mainly used for warfare and racing.

* Wagons and carriages: These became more common for transportation and hauling goods starting around 1000 BCE.

So, it's more accurate to say that the horse carriage developed gradually over thousands of years, rather than having a single year of invention.
