Strathearn

Strathearn or Strath Earn, also the Earn Valley, is the strath of the River Earn, which flows from Loch Earn to meet the River Tay in the east of Scotland.

The area covers the 30 mile stretch of the river, containing a number of settlements in Perthshire. It shares a name with a modern ward used for elections to Perth and Kinross Council.

Strathearn was also the name of a ancient province of the Kingdom of Alba, under the authority of a mormaer and then an Earl. More recently, the name has since been used in a number of titles used by the British Royal Family.

History
The historic province of Strathearn was bounded on the north by Atholl, north west by Breadalbane, south west by Menteith, south east by Fife, and on the east by Perthia.

The earliest attested mormaer of Strathearn is Mael Ísu I, who is recorded fighting alongside David I at the Battle of the Standard in 1138. Unlike some provinces where the holder of the office of mormaer rotated between kin-groups, the mormaership of Strathearn was dominated by a single family, with a Mael Ísu in every generation until the death of Mael Ísu V in the mid 14th century.

Battle of Strathearn
In 904, during the reign of Constantine II of Scotland, sons of Bárid mac Ímair sent a Danish army to attack Strathearn, and were ultimately defeated, the Kingdom of Scotland wasn't attacked by Vikings for the next 50 years.

Modern administrative history
Strathearn became a stewartry under the authority of the Earls of Perth and part of Perthshire for administrative purposes, until the abolition of heritable jurisdictions in 1748. It continued to be recognised as one of the ancient divisions of the county, without administrative or judicial function.

The Strathearn ward of Perth and Kinross Council was created in 2007.

The primary settlements of Strathearn are:
 * Lochearnhead
 * St Fillans

Royal title
Following the demise of the ancient Earls of Strathearn, with the title in its later creation being forfeited by Walter Stewart, Earl of Atholl, the Strathearn title was resurrected for use for a number of Royal dukedoms, awarded to members of the British Royal Family.

The name appeared in the titles of the Duke of Cumberland and Strathearn, Duke of Kent and Strathearn] and [[Duke of Connaught and Strathearn.

More recently, Prince William, now Prince of Wales and Duke of Rothesay, was created Earl of Strathearn, as a subsidiary title to Duke of Cambridge, on 29 April 2011, the day of his wedding to Catherine Middleton.
