It originated in Europe and was introduced to Britain by Vikings raiding its coasts. They brought with them small ‘dun-coloured’ (grey-gold or tan) and hornless cattle, which bred with the native black horned Celtic cattle of inland Scotland and produced a hornless black breed, the Aberdeen Angus. Their red colouring is believed to have come from cross-breeding with English longhorns in the 18th century producing primarily black cattle that carried a red gene. Red calves initially occurred in about 25% of births, however if red cattle were crossed then their offspring would be red as well. Red Angus cattle have all the attributes of Angus cattle with advantages for the Australian environment including higher heat tolerance and fewer issues with Buffalo Fly.
