SHORLISTED FOR THE ORWELL PRIZE 2018 NEW STATESMAN AND EVENING STANDARD BOOKS OF THE YEAR 2017 'Brilliant ... a staggering story' Robert Fox, Evening Standard, Books of the Year 'Fascinating, vast and rich ... a dramatic family memoir' Guardian Uncovering his family's remarkable and moving stories, Mark Mazower recounts the sacrifices and silences that marked a generation and their descendants. It was a family that fate drove into the siege of Stalingrad, the Vilna ghetto, occupied Paris, and even into the ranks of the Wehrmacht . His British father was the lucky one, the son of Russian Jewish emigrants who settled in London after escaping the civil war and revolution. Max, the grandfather, had started out as a socialist and manned the barricades against tsarist troops, but never spoke of it. His wife, Frouma, came from a family ravaged by the Great Terror yet somehow making their way in Soviet society. In the centenary of the Russian Revolution, What You Did Not Tell recounts a brand of socialism erased from memory - humanistic, impassioned, and broad-ranging in its sympathies. But it also explores the unexpected happiness that may await history's losers, the power of friendship, and the love of place that allowed Max and Frouma's son to call England home.

Henryk Grossman is best-known as a Marxist economist but he also wrote valuable political texts as a leader of the revolutionary organisation of Jewish workers in the Polish province of Austria, before the First World War, as a member of the Communist Workers Party of Poland, during the early 1920s, and as a Marxist academic during the early 1930s. These writings dealt with the political situation, tactics and strategy of Jewish Social Democratic Party of Galicia, the initial reception of Marxism in Poland and then substantial entries on left wing movements, organisations and individuals in a multi-volume reference work.

The Jewish experience on Polish lands is often viewed backwards through the lens of the Holocaust and the ethnic rivalries that escalated in the period between the two world wars. Critical to the history of Polish-Jewish relations, however, is the period prior to World War I when the emergence of mass electoral politics in Czarist Russia led to the consolidation of modern political parties. Using sources published in Polish, Yiddish, Hebrew, and Russian, Joshua D. Zimmerman has compiled a full-length English-language study of the relations between the two dominant progressive movements in Russian Poland. He examines the Polish Socialist Party (PPS), which sought social emancipation and equal civil rights for minority nationalities, including Jews, under a democratic Polish republic, and the Jewish Labor Bund, which declared that Jews were a nation distinct from Poles and Russians and advocated cultural autonomy. By 1905, the PPS abandoned its call for Jewish assimilation, and recognized Jews as a separate nationality. Zimmerman demonstrates persuasively that Polish history in Czarist Russia cannot be fully understood without studying the Jewish influence and that Jewish history was equally infused with the Polish influence.
