Tribes settled in an area, bred more people due to the increased food supply, and eventually built a city. Without exception, the city always developed a form of governance that qualifies as a state.
It's not because people had a particular attitude towards the technology of agriculture (unless you include in that "we can have more kids because there's plenty of food"). It's that such a large number of people could not operate by informal means.
As the classical pattern of civilization consolidated, near-universal patterns of government arose: monarchy, hereditary warrior-landholder aristocracy, slavery or serfdom, state religion based around common religious ideas (Gods-over-man, man-over-woman, man-over-nature, some-men-over-others). Other technologies were developed without affecting this pattern (writing, the wheel, metal working, sailing). The only major exceptions to this pattern, such as Athenian democracy and the Roman Republic, emerged in situations where commerce became more important than agriculture as a source of wealth. Much later, another complex of technologies (the printing press, the scientific method, the steam engine, the assembly line) led to the industrial revolution, which boosted the importance of commerce over agriculture and led to a change in government type and the end of slavery, serfdom, and hereditary nobility (except in vestigial form in some countries).
