Earl of Breadalbane and Holland is a title in the Peerage of Scotland. It was created in 1681 for Sir John Campbell, 5th Baronet, of Glenorchy, who had previously been deprived of the title Earl of Caithness. He, as a principal creditor, had "acquired" the estates of George Sinclair, 6th Earl of Caithness who had died heavily in debt and without issue in 1670. Campbell was consequently created Earl of Caithness in 1673, but after much litigation and even bloodshed, George Sinclair of Keiss (died 1698), second son of George, 5th Earl of Caithness (died 1643), recovered the estates, and successfully petitioned parliament regarding the earldom, which was removed from Campbell. Sinclair's title was finally restored to him in 1681. Deprived by parliament of the Caithness earldom, Sir John Campbell was created on Lord Glenorchy, Benederaloch, Ormelie and Weick, Viscount of Tay and Paintland, and Earl of Breadalbane and Holland on 13 August 1681, with the precedency of the former patent and with the power to nominate any of his sons by his first wife to succeed him. The titles were created with remainder to the heirs male of the son chosen to succeed him, failing which to the heirs male of his body, failing which to his own heirs male, failing which to his heirs whatsoever. The "of Holland" part of the title derived from the fact that Campbell was the husband of Lady Mary Rich, daughter of Henry Rich, 1st Earl of Holland (see Earl of Holland).
The member of a junior branch of Clan Campbell, Breadalbane was a descendant of Sir Colin Campbell, 1st of Glenorchy (died 1475), the son of Duncan Campbell, 1st Lord Campbell by his second wife Margaret Stewart and the half-brother of Archibald Campbell, Master of Campbell, ancestor of the Dukes of Argyll. Sir Colin Campbell was granted Glenorchy and other lands by his father and built Kilchurn Castle on Loch Awe in Argyll. His son Sir Duncan Campbell of Glenorchy was one of the many Scottish nobles killed at the Battle of Flodden in 1513. Sir Duncan's great-grandson and namesake Duncan Campbell, known as "Black Duncan", represented Argyllshire in the Scottish Parliament. He was knighted in 1590 and created a baronet, of Glenorchy in the County of Perth, in the Baronetage of Nova Scotia in 1625. His elder son, Sir Colin, the second Baronet, died childless and was succeeded by his younger brother, Sir Robert, the third Baronet. He represented Argyllshire in the Scottish Parliament. He was succeeded by his son, Sir John, the fourth Baronet. He also represented Argyllshire in Parliament. He was succeeded by his son by his first marriage, the aforementioned Sir John Campbell, the fifth Baronet, who was created Earl of Breadalbane and Holland in 1681.
