Timeline of project management
# Timeline of project management

This article covers the historical timeline of project management. There is a general understanding that the history of modern project management started around 1950. Until 1900, projects were generally managed by creative architects and engineers themselves, among those, for example, Christopher Wren, Thomas Telford and Isambard Kingdom Brunel.

## Early civilizations

* 2570 BC Great pyramid of Giza completed. Some records remain of how the work was managed: e.g. there were managers of each of the four faces of the pyramid, responsible for their completion (subproject managers).
