Northumberland County Flag Lapel Pin Badge.
The Northumberland flag is based on a traditional flag which is probably the oldest known flag design in Britain. The Venerable Bede, England's first historian, records a banner of purple and gold hung over the tomb of St Oswald, the 7th century King of Northumbria. The flag for this ancient kingdom is now generally regarded as having eight alternate stripes of red and gold. Later, in medieval times, the colours were adopted by the first Earl of Northumberland.
