Politics, architecture, landscapes, city designs and infrastructure planning were the substance of the earl of Mar’s creative thinking before and after the Anglo-Scottish Union of 1707. Condemned as a traitor after he led and lost the Jacobite Rising of 1715, Mar devoted his time in exile to creating a new constitution for the UK in which England, Ireland and Scotland would become equal partners in a federation with France for the enduring peace of Europe. Richly illustrated with Mar’s magnificent designs for cities, palaces and houses, this is the first book about this controversial figure.
