the.com/centralization

means The process of pulling power, control, or decision-making away from many scattered points and concentrating it in one central authority.

from Built from 'center' (Latin centrum, from Greek kentron, the sharp point of a compass used to draw a circle — the fixed spot everything else revolves around) plus the '-ize/-ization' pattern that turns a noun into 'the process of making so.' The word itself took shape in the early 1800s, rising alongside modern states and bureaucracies that were busy doing exactly this — gathering administration, finance, and authority out of the provinces and into a capital. So the term is almost as young as the habit it names: the drawing of everything toward one fixed point.
