At the age of 17, Mercury and his family fled from Zanzibar for safety reasons due to the 1964 Zanzibar Revolution, in which thousands of Arabs and Indians were killed.The family moved into a small house in Feltham, Middlesex, England. Mercury enrolled at Isleworth Polytechnic (now West Thames College) in West London where he studied art. He ultimately earned a diploma in Art and Graphic Design at Ealing Art College(now the Ealing campus of University of West London), later using these skills to design the Queen crest. A British citizen at birth, Mercury remained so for the rest of his life.
