Today is the birthday of the grandson of Leon Trotsky, Esteban Volkov. Over the course of his life, Volkov has fought to preserve the historical truth about Trotsky’s life and work, against the smears of the Stalinists and bourgeois historians. In particular, Volkov has preserved a unique monument to Trotsky’s legacy: the Leon Trotsky House Museum in Coyoacán, Mexico, which was once home to Volkov and his grandparents, Natalia Sedova and Leon Trotsky. On the occasion of his birthday, the International Marxist Tendency would like to send revolutionary greetings to this lifelong champion of Trotsky’s legacy.
