CAMPBELL, Archibald, third Duke of Argyll, brother of the preceding, was born at Hamhouse, in England, in June 1682, and was educated at the University of Glasgow. He afterwards applied himself to the study of the civil law at Utrecht; but, upon his father's being created a duke, he betook himself to a military life, and served some time under the Duke of Marlborough. Upon quitting the army, in which he did not remain long, he applied to the acquisition of the knowledge calculated to enable him to perform a part in the political world. In 1705 he was appointed treasurer of Scotland, and made a considerable figure in parliament, though he was not more than twenty-three years of age. In 1706 he was appointed one of the commissioners for treating of the union; and in the
Campbell, same year he was created Lord Oronsay, Dunoon, and Ar-
rois, Viscount and Earl of Isla. In 1708 he was made an
extraordinary lord of session; and when the union had
been effected, he was chosen one of the sixteen peers for
Scotland in the first parliament of Great Britain, and was
elected to every future parliament, except the fourth, till
his death. In 1710 he was appointed justice-general of
Scotland. In 1711 he was called to the privy council; and
upon the accession of George I. he was nominated lord
register of Scotland. When the rebellion broke out in
1715, he again betook himself to arms, in defence of the
house of Hanover, and by his prudent conduct in the West
Highlands, he prevented General Gordon, at the head of
three thousand men, from penetrating into the country
and raising levies. He afterwards joined his brother at
Stirling, and was wounded at the battle of Dumblane or
Sheriffmuir. He was appointed keeper of the privy seal
in 1725, and from this time he was intrusted with the
management of Scottish affairs. In 1734, upon his re-
signing the privy seal, he was made keeper of the great
seal, which office he enjoyed till his death. Upon the
decease of his brother, he became Duke of Argyll, heredi-
tary justice-general, lieutenant, sheriff, and commissary
of Argyleshire and the Western Isles, hereditary great
master of the household, and hereditary keeper of Dun-
staffnage, Carrick, and several other castles. He was also
chancellor of the University of Aberdeen, and laboured
to promote the interest of that, as well as of the other
universities of Scotland. It was by his advice that, after
the rebellion in 1745, the Highlanders were employed in
the royal army. He was a man of great endowments,
both natural and acquired, and possessed considerable
parliamentary abilities. He was likewise eminent for his
literary accomplishments, and had collected one of the
most valuable private libraries in Great Britain. The fa-
culties of his mind continued unimpaired till his death,
which happened suddenly on the 15th of April 1561, in
the seventy-ninth year of his age. He was married, but
had no issue; and was succeeded in his titles and estates
by John Campbell, fourth Duke of Argyll, son of the
honourable John Campbell of Mammore, the second son
of Archibald the ninth Earl of Argyll. The family of Ar-
gyll were heritable justices-general for Scotland till the
office was abolished by the jurisdiction act. They are
still heritable masters of the king's household in Scotland,
and keepers of Dunstaffnage and Carrick.
