Standing Council of Clan Chiefs secretary Romilly Squire explains the origins of the clan system in Scotland.
"It came about when you had groups of people living close to one another, thieving off one another and taking any excuse to beat each other up," Squire said.The newly installed chief of the MacDonald clan is Ranald Alasdair MacDonald—a 76-year-old retired audiologist. In his defense, he was known as the meanest son of a bitch to ever practice audiology in Edinburgh.
"Originally the clan chief was elected and it was usually the meanest son of a bitch who got the job. He offered to protect the clan in return for service to the larger group." [Link]
