Modern Era
Łódź transformed from a sleepy village into Poland's industrial powerhouse during the nineteenth century, drawing tens of thousands of Jewish workers and entrepreneurs who built textile mills, factories, and a thriving mercantile class under Russian imperial rule. By 1900, Jews comprised nearly half the city's population—a dense, energetic community speaking Yiddish in crowded tenements alongside Polish and German speakers. The city became a crucible of modern Jewish thought: religious Orthodoxy, Hasidic devotion, socialist movements, and Zionist ambitions competed for souls in synagogues, study halls, and underground presses. The Great Synagogue on Wolborska Street stood as a monument to this prosperity and aspiration, its Neo-Gothic spires visible across the industrial landscape of smokestacks and mill wheels. Yet this golden age proved fragile; after the Russian Revolution of 1917, economic decline set in, and by the 1930s poverty and political antisemitism shadowed the community—a prelude to the devastation of the Holocaust, which would nearly erase Łódź's once-vibrant Jewish world.
