In medieval India, administrative divisions were structured hierarchically, with "Paragana" being the smallest unit, followed by "Sarkar," and then "Suba," the largest. A "Paragana" comprised several villages and was primarily for revenue administration; "Sarkar" was an aggregation of multiple Paraganas, which facilitated broader governance; and a "Suba" encompassed several Sarkars, serving as a provincial administrative unit. This ascending order reflects the increasing scale of administrative organization and governance complexity in the medieval period, as detailed in NCERT textbooks and other standard references for UPSC preparation.
