The epistolary legacy of Ilya Ehrenburg is being published for the first time and includes both letters scattered across hard-to-find periodicals and those published here for the first time. The writer’s fate was such that he found himself at the epicenter of the most significant events of his time, therefore the letters, arranged chronologically, provide an impressive panorama of wars and revolutions, the flowering of world avant-garde art. At the same time, they contain unique material on the history of literature, covering various political eras. The first volume includes 600 letters from 1908–1930, when the writer mostly lived abroad (in Paris, in Berlin, again in Paris); This is an almost complete set of Ehrenburg’s letters from those years that have now been identified. The letters are addressed to Russian and foreign poets, writers, artists, theater and film workers, and famous politicians. The publication contains an extensive scientific apparatus.
