By 1850, there were 1 million people living in Paris, and the population overflowed into the streets. Movement on the street was at a standstill, and trade was impossible—the nephew of Napoleon Bonaparte. Napoleon, the third came up with a dramatic plan to rebuild Paris by widening streets, improving traffic flow and clearing the slums. Haussmann decided to buy up the land and move the slums and their inhabitants to the outskirts of the city. Now, he can focus on public transportation problem. By easing traffic conditions, he felt he was organising Paris and opening it up to an economic boost. Since the slums have been torn down, he had room to construct condominiums in their stead. He was very interested in giving Paris a modern look. Every apartment building was constructed to Haussmann's standards.
