The Origin of ‘Beating a Dead Horse’:
There are several phrases and sayings in use today that originated from the activity of horse racing. It’s possible that this one comes from it as well. How so? Well, during a horse race, a jockey may have access to a riding crop, which kind of looks like a miniature whip. The jockey uses the riding crop to hit or “beat” the horse on the thigh in an effort to get them running faster.
While there is controversy involved with how horses are treated during races, the purpose of “beating” a horse during this activity is to acquire more speed. However, what would be the point of beating a dead horse? There wouldn’t be one; it’d be pointless! So while beating a living horse serves a purpose, beating a dead one would be nothing more than futile.
Anyways, this saying dates back to at least the year 1859. A form of it makes an appearance in the London newspaper Watchman And Wesleyan Advertiser. There’s an article from the newspaper that reads:
“It was notorious that Mr.Bright was dissatisfied with his winter reform campaign and rumor said that he had given up his effort with the exclamation that it was like flogging a dead horse.”
The word ‘flogging’ is just another word for beating.

Note: While this is not the case for all phrases and sayings, sometimes their origin is unknown. When that happens, if there are explanations floating around that speculate on its origin, these may be listed. However, if no explanation is given, there should still be an old quote of the idiom being used in print. This can give you an idea on how old it is.
