In OTL, one of the biggest reasons for the disintigraton of Highland traditions like the Clan system was the government backlash against the Highlanders after the Jacobite Rebellion in 1745. But assuming, for some reason (Bonnie Prince Charlie's ship is sunk, Prince James gives birth to a daughter, etc) the Jacobites never rebel, what would be the fate of the Highlands? How long would the clan system last?
