  Cyrus founded the empire as a multi- state empire governed by four capital states; Pasargadae, Babylon, Susa and Ecbatana. He allowed a certain amount of regional autonomy in each state, in the form of a satrapy system. A satrapy was an administrative unit, usually organized on a geographical basis. A ' satrap ' (governor) was the vassal king, who administered the region, a 'general' supervised military recruitment and ensured order, and a 'state secretary' kept the official records. The general and the state secretary reported directly to the satrap as well as the central government.
  
  During his reign, Cyrus maintained control over a vast region of conquered kingdoms, achieved through retaining and expanding the satrapies. Further organization of newly conquered territories into provinces ruled by satraps was continued by Cyrus's successor, Darius the Great. Cyrus's empire was based on tribute and conscripts from the many parts of his realm.
  
  Through his military savvy, Cyrus created an organized army including the Immortals unit, consisting of 10,000 highly trained soldiers. He also formed an innovative postal system throughout the empire, based on several relay stations called Chapar Khaneh.
  
  Cyrus's conquests began a new era in the age of empire building, where a vast superstate, comprising many dozens of countries, races, religions, and languages, were ruled under a single administration headed by a central government. This system lasted for centuries, and was retained both by the invading Seleucid dynasty during their control of Persia, and later Iranian dynasties including the Parthians and Sasanians.
  
  Cyrus has been known for his innovations in building projects; he further developed the technologies that he found in the conquered cultures and applied them in building the palaces of Pasargadae. He was also famous for his love of gardens; the recent excavations in his capital city has revealed the existence of the Pasargadae Persian Garden and a network of irrigation canals. Pasargadae was a place for two magnificent palaces surrounded by a majestic royal park and vast formal gardens; among them was the four-quartered wall gardens of " Paradisia " with over 1000 meters of channels made out of carved limestone, designed to fill small basins at every 16 meters and water various types of wild and domestic flora. The design and concept of Paradisia were exceptional and have been used as a model for many ancient and modern parks, ever since.
  
  The English physician and philosopher Sir Thomas Browne penned a discourse entitled The Garden of Cyrus in 1658 in which Cyrus is depicted as an archetypal wise ruler – while the Protectorate of Cromwell ruled Britain. However, despite being featured in the title, Cyrus was not a main focus of Browne's work.
  
  "Cyrus the elder, brought up in Woods and Mountains, when time and power enabled, pursued the dictate of his education, and brought the treasures of the field into rule and circum-scription. So nobly beautifying the hanging Gardens of Babylon, that he was also thought to be the authour thereof."
  
  Cyrus's standard, described as a golden eagle mounted upon a "lofty shaft", remained the official banner of the Achaemenids.
