The rise to power of the Tokugawa Shogunate marked an end to the internal strife and warfare that had characterized the preceding century.

There are few main ideas regarding the relationships between these two geographical areas. According to Algaze, the Susiana was colonized by group of people from southern Mesopotamia in the Uruk period and he indicates cultural homogeneity these two lands in Uruk period. §REF§ Algaze 1993, 15-17 §REF§ The opposite opinion is presented by Amiet, who suggested that Susiana was inhabited by two different 'ethnic' group (so called - 'Elamite' and 'Mesopotamian' type). The culture of this land, hence, was seen as some kind of hybrid and the alternately appearance of 'Elamite' or 'Mesopotamian' cultural elements is related to some sort of 'fashion' or 'trends'. §REF§ Amiet 1979 §REF§ , §REF§ Amiet 1992: 80 §REF§ The Uruk polity is perceived by Algaze as some kind of proto-state organism and he describes it as “an early instance of an \"informal empire\" or \"world system\" based on asymmetrical exchange and a hierarchically organized international division of labour that differs from modern examples only in degree.” §REF§ Algaze 1989, 571 §REF§ He emphasizes very rapid and intense cultural growth of Uruk polity and he considers few types of Uruk expansions: “(1)new form of spatial distribution: the growth of cities and their dependencies; (2)new form of socio-political organization: the explosive growth of social differentiation, the emergence of encumbered labour, and the crystallization of the state; (3) new forms of economic arrangements and of record keeping: state control of a substantial portion of the means of production and of its surplus, craft and occupational specialization on an industrial scale; and, finally, (4)the new forms of symbolic representation needed to validate the changes taking place in the realm of social and political relationship-leading to the creation of an artistic tradition and iconographical repertoire that were to set the framework for pictorial representation in Mesopotamia for millennium to come.” §REF§ Algaze 1989, 590-91 §REF§ There are many hypotheses regarding the political system of Uruk polity. Most of the researchers (e. g. Frangipane, Rothman, Pollock, Wright) perceived the Uruk polity as some kind of united (in cultural sense) community which shares number of features (particularly in material culture) and they represent some early stage of city-state organization with dominant position of some cities and the group of elite. §REF§ Nissen 2001, 161 §REF§ , §REF§ Pollock 2001, 181-233 §REF§ However, other archaeologists believed (e. g. Algaze) that some cities have been already ruled by one person - ruler which collected all political, religious and military power. There are many images of this person on seals, sealing, vase, furniture inlays where he is showed as a warrior, bearded man in cap, hunter and master of animals. Algaze even writes: “comparison with inscribed statues of later Sumerian rulers in strikingly similar poses leaves no doubt that the analogous Uruk-period images are stylized and standardized representations of kings.” §REF§ Algaze 2001, 34 §REF§ ", "shapefile_name": null, "private_comment": null, "created_date": null, "modified_date": null, "home_nga": { "id": 8, "name": "Southern Mesopotamia", "subregion": "Levant-Mesopotamia", "longitude": "44.420000000000", "latitude": "32.470000000000", "capital_city": "Babylon (Hillah)", "nga_code": "IQ", "fao_country": "Iraq", "world_region": "Southwest Asia" }, "home_seshat_region": { "id": 62, "name": "Mesopotamia", "subregions_list": "Iraq, Kuwait", "mac_region": { "id": 11, "name": "Southwest Asia" } }, "private_comment_n": { "id": 1, "text": "NO_PRIVATE_COMMENTS" } }, "comment": null, "private_comment": { "id": 1, "text": "NO_PRIVATE_COMMENTS" }, "citations": [], "curator": [] }, { "id": 668, "year_from": 1787, "year_to": 1787, "description": "The total population of Spain and Spanish held lands in 1787 is estimated at around 10,318,000 inhabitants.”<ref>(Casey 2002: 21) Casey, James. 2002.
