[1] It was created in 1900 for the Scottish-born Canadian financier and politician Donald Smith, 1st Baron Strathcona and Mount Royal,[2] with remainder in default of legitimate male issue to his only daughter, Margaret Charlotte.

Their eldest son, the third Baron, represented North Cumberland in the British House of Commons as a Unionist from 1922 to 1926.

The latter's son, the fourth Baron, succeeded in 1959 and served under Margaret Thatcher as a Minister of State at the Ministry of Defence from 1979 to 1981.

[4] Accordingly, Sheffield-Sterling-Strathcona Hall, a classroom and administration building on Yale's campus, is partially named in his honour.
