Ebenezer Howard proposed the Garden City movement to address problems with cities and rural life. He envisioned self-sufficient, planned communities that blended the best of urban and rural living. His influential book Tomorrow: A Peaceful Path to Real Reform outlined a model garden city of 32,000 residents surrounded by a greenbelt. The first realizations were Letchworth Garden City in 1903 and Welwyn Garden City in 1920, which aimed to apply Howard's principles of balanced communities integrated with nature.
