The Most Ancient and Most Noble Order of the Thistle is an order of chivalry associated with Scotland. The current version of the order was founded in 1687 by King James VII of Scotland, who asserted that he was reviving an earlier order. The order consists of the sovereign and sixteen knights and ladies, as well as certain "extra" knights. The sovereign alone grants membership of the order; they are not advised by the government, as occurs with most other orders.
