Define bureaucracy in political systems through the age of enlightenment

Although the term "bureaucracy" was not coined until the mid 18th century, organized and consistent administrative systems are much older. The development of writing (ca. 3500 BC) and the use of documents was critical to the administration of this system, and the first definitive emergence of bureaucracy is in ancient Sumer, where an emergent class of scribes used clay tablets to administer the harvest and allocate its spoils. Ancient Egypt also had a hereditary class of scribes that administered the civil service bureaucracy.
