Iron Age II is considered the classical period of the Iron Age (figure: 2). This period shows sudden increase in distribution and diversification in settlement pattern, in South-eastern Arabia (Magee 1998b:49). The settlements during this period expanded to include inland (Herrmann et al. 2012), mountains (Haser in Avanzini 2010:162) and coastal sites (Mouton & Schiettecatte 2014). Settlements became more diverse to include non-residential architecture. An appearance of irrigation technology (Falaj) along with camel domestication coincides with this increase. This increase was accompanied by regional (Benoist & Mery 2012: 88) (between the varied types of settlements) and trans-regional contact (with south Arabia) and goods exchange (Magee 1999, 2004, 2005).The layout, the location, the structure and the material culture excavated from this period reflects a complex community (Magee & Thompson 2001:129) (Magee 1998b:54). This manifested in the appearance of a belief system related to both irrigation and bronze production (the snake cult) (Benoist 2007:50), specialized labour in pottery (Benoist & Mery 2012:88), metal production (Magee 1998a:114) (Nashef in Avanzini 2010:215) and administration systems (al-Tikriti 2010:240), fortification structures related to the agriculture activity (Magee 2014:237), symbolic (axe heads on the stamp seals) and prestigious goods for elites (Magee 1998b:56). This paper argues that irrigation technology was responsible for creating a social elite class. This class was responsible for cyclic production, the expansion and the diversification of settlement patterns using the domestication of the camel.The Iron Age is divided into three sub periods based on ceramic evidence from Tell Abraq: I (1200–1000 BC), II (1000–600 BC) and III (600–300 BC) (Magee 2001:345).Table 1: Brief description of the settlement patterns and economy of Iron Age I and III: Iron Age I(1300-1000BC) Iron Age III(600-300BC) Settlement Patterns Known Shimal, Tell Abraq, al- One-third reduction in number Hamriyah and possibly Kalba; of sites when compared with on the Gulf coast, and the East Iron Age II.
