Kurdish was a term I heard long before I had any real sense of the world, of where Iran, Iraq, Syria and Turkey are, or what cultural and religious intolerance mean. When I was about 7, a Kurdish girl called Hozan showed me how her people danced at weddings and at great moments of celebration, stamping, swirling and clicking her tongue. She was 15, and to me she was glamour personified, spinning in a field, her tiny denim shorts alarmingly far up her bottom, her head thrown back. This was in the mid-Seventies, in Oxfordshire, and Hozan’s family was encamped with some local Romany gypsies. At about the same time, in March 1975, the Shah of Iran signed a treaty with Saddam Hussein. The Kurds of Iraq thereby lost all their external support. And so they began to be exterminated.
