Constantinos A. Doxiadis, an architect-engineer born in 1913, specialized in urban planning and introduced the concept of the 'dynamic city,' which evolves through four stages: dynapolis, dynametropolis, dynamegopolis, and ecumenopolis. Each metropolis has unique characteristics and center systems, and Doxiadis emphasized the need for tailored solutions in urban development. His master plan for Islamabad reflected these principles, allowing the city to expand dynamically towards its cores.
