Noble titles created in 1581

The title Earl of Morton was created in the Peerage of Scotland in 1458 for James Douglas of Dalkeith. Along with it, the title Lord Aberdour was granted. This latter title is the courtesy title for the eldest son and heir to the Earl of Morton.

Earl of March is a title that has been created several times, respectively, in the Peerage of Scotland and the Peerage of England. The title derives from the "marches" or borderlands between England and either Wales (Welsh Marches) or Scotland (Scottish Marches), and it was held by several great feudal families which owned lands in those districts. Later, however, the title came to be granted as an honorary dignity, and ceased to carry any associated power in the marches.

Earl of Orkney, historically Jarl of Orkney, is a title of nobility encompassing the archipelagoes of Orkney and Shetland, which comprise the Northern Isles of Scotland. Originally founded by Norse invaders, the status of the rulers of the Northern Isles as Norwegian vassals was formalised in 1195. Although the Old Norse term jarl is etymologically related to "earl", and the jarls were succeeded by earls in the late 15th century, a Norwegian jarl is not the same thing. In the Norse context the distinction between jarls and kings did not become significant until the late 11th century and the early jarls would therefore have had considerable independence of action until that time. The position of Jarl of Orkney was eventually the most senior rank in medieval Norway except for the king himself.

The title Duke of Lennox has been created several times in the peerage of Scotland, for Clan Stewart of Darnley. The dukedom, named for the district of Lennox in Dumbarton, was first created in 1581, and had formerly been the Earldom of Lennox. The second duke was made Duke of Richmond; at his death, the dukedom of Richmond became extinct. The fourth duke was also created Duke of Richmond; at the death of the sixth duke, both dukedoms became extinct. The Dukedom of Richmond and one month later that of Lennox were created in 1675 for Charles Lennox, an illegitimate son of Charles II. The Duke of Richmond and Lennox was created Duke of Gordon in 1876. Thus, the duke holds four dukedoms (if including Aubigny-sur-Nère), more than any other person in the realm; or (not counting the putative French title) three, equal since 2022 to Prince William, Duke of Cornwall, of Rothesay and of Cambridge.

Earl of Gowrie is a title that has been created twice, once in the Peerage of Scotland and once in the Peerage of the United Kingdom, both times for members of the Ruthven family. It takes its name from Gowrie, a historical region and ancient province of Scotland. On 23 August 1581, William Ruthven, 4th Lord Ruthven, was created Earl of Gowrie by James VI, King of the Scots. He was executed for high treason, attainted and his peerages forfeited on 28 May 1584. Two years later in 1586, the attainder was reversed and his son, the second Earl, was restored as Earl of Gowrie and Lord Ruthven, but both peerages were forfeited after the alleged plot and subsequent death of the second Earl's younger brother, the third Earl, in 1600.
