supposedly it was william the conqueror (1066?) who claimed england belonged to him, split it between his cronies, . So, his cronies found that deer meat would fetch good money so arranged forests so that they could hunt deer better, and people were no longer allowed to forage in the forests to live, in case it affected the deerhunting. so they had to work for the landowner, or get branded/hung etc, to survive.

Nah, hunting forests predate the Normans by at least a couple of centuries, if not more. King Alfred the Great had a hunting lodge in Chippenham, his hunting grounds and forests were extensive, there’s a Forest Lane running from Lacock into Melksham, with an area of Melksham called Forest, and Chippenham was a major Saxon administrative centre by 853. There were major skirmishes with Viking invaders in and around Chippenham, until Alfred beat them into submission at Eddington in 878.
There’s a fair bit about the early history of the area here:
