There are around 300,000 Romani Gypsies in the UK. They are originally from Northern India and arrived in Britain at the beginning of the 16th century. Irish Travellers (their number is estimated to 30 000 in the UK) arrived much later, mainly in the 20th century and are of Irish origin. Both groups are nomadic although, nowadays, only about 50 % of Gypsies and Travellers in Britain live in caravans. Even if they live in a house, they take their culture inside with them. Yet from different origins, Romani Gypsies and Irish Travellers have always lived alongside and inter-married with each other.
