The arms were officially granted on January 23, 1951.
The two upper divisions represent the principalities of Powys Wenwynwyn and Powys Fadog, which in the Middle Ages covered largely what is now Montgomeryshire. The red lion on gold was the traditional arms of Gwenwynwyn and the black lion on white those of Madog, the two respective Princes descended from Bleddyn ap Cynfyn, last Prince of Powys. The gold lion on blue is from the arms of Roger de Montgomery, Earl of Shrewsbury, a leader of the Norman invasion of Wales, from whom the town and county take their name. The black and white border is derived from the colours of Brochwel Ysgithrog, a 7th century Prince of Powys famous for his resistance to the Saxons.
The red mural crown represents Powys Castle (Castell Coch - Red Castle) and the swan is for the beautiful waterways of the county, particularly the rivers Severn and Wye. The branch of oak recalls the former importance of Montgomeryshire oak to the Royal Navy.
The green wyverns derive from the crest of the Herberts, Earls of Powis and Montgomery. The golden fleeces hanging from their necks refer to the former woollen industry.
The motto is that long used in the county before the arms were granted.
