Abdulrazak Gurnah in Granta:
I first came across Friedrich Schiller and his work in the aftermath of the revolution in Zanzibar in January 1964. Among the victorious insurgents was a left-leaning group called the Umma Party. There is a long tale to be told about the formation of this group and its fate. In the early 1960s, members of the Umma, right under the eyes of the British colonial administration, went off to Cuba for military training. The connection with Cuba meant that the Umma had friends and supporters in the Soviet bloc of nations. After the revolution, the group had significant influence in the new power-balance in the government. It was no doubt through the influence of the Umma faction, as well as through expediency, that the post-revolutionary government invited or accepted the fraternal assistance of the ‘socialist’ group of nations.
Our newly-created army was soon wearing Cuban-style forage caps and marching the Soviet goose-step.
