How did the social structure in Ancient Greece change over time

The increasing complexity of the social structure, the formation of social strata with different, conflicting interests created tension in Ancient Greece society, which, in a number of policies, grew into bloody clashes, leading to murders, expulsion, and confiscation of property. These social clashes were caused by the desire to implement a certain socio-political program for the development of a polis. If the military-agricultural aristocracy stood for the adaptation of the tribal system, traditional management institutions to the new conditions, since namely they guaranteed the aristocracy the preservation of its privileges, influence and political power, then the broad masses of farmers, trade and craft circles (unlike the aristocracy, this part people called demos, i. e., people) sought to create new governing bodies in which they could directly participate and which could guarantee them approval private property, rapid economic development, widespread use of slave labor, their personal freedom. History of Greece in 8-6 centuries BC is filled with clashes over the implementation of these development programs. In the 8th - first half of the 7th century BC the military-landowning nobility maintained a dominant position, but, from the middle of the 7th century BC, the political influence of the aristocracy weakened, and its opponents from the midst of the demos gradually pushed the tribal nobility from the dominant position and increased their political influence.
