What did the earliest civilized groups accomplish?

Civilizations are intimately associated with and often further defined by other socio-politico-economic characteristics, including centralization, the domestication of both humans and other organisms, specialization of labour, culturally ingrained ideologies of progress and supremacism, monumentalarchitecture, taxation, societal dependence upon farming and expansionism.[2][3][4][6][7][8] Historically, civilization has often been understood as a larger and "more advanced" culture, in contrast to smaller, supposedly primitive cultures.[1][3][4][9] Similarly, some scholars have described civilization as being necessarily multicultural.[10] In this broad sense, a civilization contrasts with non-centralized tribal societies, including the cultures of nomadic pastoralists, Neolithic societies or hunter-gatherers, but it also contrasts with the cultures found within civilizations themselves. As an uncountable noun, "civilization" also refers to the process of a society developing into a centralized, urbanized, stratified structure. Civilizations are organized in densely populated settlements divided into hierarchical social classes with a ruling elite and subordinate urban and rural populations, which engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control
