According to the character sketch by Gilbert Burnet, bishop of Salisbury, inserted into Spring Macky’s published edition of his father’s memoirs, Lothian was a Presbyterian by family tradition and political preference rather than by religious belief: ‘laughs at all revealed religion, yet sets up for a pillar of Presbytery, and proves the surest card in their pack; being very zealous, though not devout’.
Lothian’s commitment to the Revolution could not be impugned, however. He had been ‘active … against King James’, and subsequently raised a troop of horse for William, serving in the army in Scotland throughout the king’s reign. The family were closely allied to the Argylls: Lothian had contracted to marry his first cousin, Lady Jean Campbell (out of a sense of duty, it was said), at the very time that her father was in prison in Edinburgh awaiting execution.
Lothian was invested with the Order of the Thistle at Edinburgh in November 1705, but this honour was clearly insufficient to assuage his strong sense of entitlement while the Guards colonelcy remained unfilled.
enumerating the affronts I have met with at this time which I never could have imagined. As I had the honour to be among the first that offered my service at the late happy Revolution, so, my lord, I have the misfortune to be the first who after 17 years’ service is obliged to quit the service, being so publicly disgraced in the way of my treatment; and I must say to your lordship, I cannot see wherein I have deserved it. For I can say I did my endeavour to serve the queen to my power faithfully and honestly.HMC Mar and Kellie, i. 254.
This was immediately perceived by his friends as a false move. The principal of Edinburgh University, William Carstares, tried to smooth things over with Mar, who wrote to Carstares on 25 Mar.:
You are very justly concerned for what my Lord Lothian has done, as you may be sure we are all. He has done himself a vast deal of harm by it; and I’m afraid the queen will not easily pass it over. It does harm also to others of his friends in their affairs. His commission is not yet given up to the queen, though this day we were forced to tell her of it, it became so public. I fancy the duke of Argyll will give it up one of these days; for he sees not how Lothian can retreat … I am afraid Lothian has lost himself and his pretensions, which were very good: but I hope he will still continue of the principles he professed, and by good and faithful service, regain this step.HMC Mar and Kellie, i. 256; Carstares SP, 748.
In the event, Argyll, together with Mar’s political chief, James Douglas, 2nd duke of Queensberry [S], were able to calm the situation, and prevent the ultimatum from being delivered to the queen. By the time the Scottish Parliament met in the winter of 1706–7 to debate the treaty, Lothian had been brought round by Argyll to vote a strongly court line in favour of union. As a reward, he finally received his Guards commission, and, at Argyll’s earnest request, was included in the first cohort of representative peers to sit in the united Parliament.
He took his seat in the Lords on 23 Oct. 1707, alongside Argyll’s brother, Archibald Campbell, earl of Ilay [S]. He attended for 71 per cent of sittings in this Parliament and 25 per cent in the following session 1708-9 (in which his participation was foreshortened), and in total was named to fewer than 10 committees. There is no evidence that he registered his proxy. His only distinctive contribution in the 1707–8 Parliament occurred on 7 Feb. 1708, when he signed a protest against the Squadrone-inspired bill to abolish the Scottish Privy Council. He was also present on 11 Mar., when the queen refused the royal assent to the Scottish militia bill. The announcement that day of a French fleet having set sail for Scotland prompted his departure to join his regiment, and the following month he was present at a meeting at Edinburgh where an address was drawn up ‘asserting her majesty’s right against the prince of Wales and all pretenders whatsoever’.
Lothian attended the first election of representative peers on 17 June 1708, where he was one of the successful candidates on the court slate.
In 1710 Lothian followed Argyll in switching his political allegiance to the Tories. By October he was writing to Robert Harley, later earl of Oxford, for help in getting a Guards company for his son-in-law (a request which he had previously made of John Churchill, duke of Marlborough) and asking for Harley’s instructions on how to proceed in the election for representative peers.
Lothian was elected again as a representative peer in 1715 (on the court list agreed by Argyll and the Squadrone).
