What factors contribute to the increased rigidity of racial segregation and renewed white efforts to exclude blacks from political life in the late 1800s?

One of the main factors is the return to power of white Democratic Party politicians in state legislatures soon after the Reconstruction. At that time, the Democrats were pro-slavery and pro-segregation (President Lincoln is a Republican). Those white pro-slavery democrats want to restrict the rights of now free blacks and so worked hard to pass the so-called Jim Crow laws in state and local governments, and they formed militias to intimidate black voters and political opponents.

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
