This chapter offers a chronological guide, a kind of compass, and a concise historical outline. Here, one can find events on an international scale which set the conditions that shaped history. They range from the French Revolution, world wars and international treaties, to innovatory actions that explain developments in planning law and practice. The chronology also includes turning points in the regulation of planning and cities, like the Baron Haussmann’sHaussmann interventions in ParisParis, the conceptions of town planning of Utopian thinkers, the new towns built by Russian emperors, the design of famous open spaces and squares in Britain or Spain, the relegation of powers to German local municipalities, the British Garden Cities, and the zoning ordinances in Germany and the United States. These are just a few examples of what the reader will find in the chronological tables.
