In the 19th century, Paris was becoming one of the most famous cities in the world, filled with grand boulevards, elegant buildings, cafés, theaters, and growing wealth. But behind the beautiful image of the City of Light was another Paris — crowded neighborhoods where working-class families struggled with poverty, poor sanitation, dangerous work, and difficult living conditions.
