I believe this is sufficiently exhibited by 18th-19th century imperial powers that have telegraphs and able to have the centre dictate unit movements and campaigns to the peripheries. Compared to previous eras where the local potentate is the ultimate source of order - at least for short and medium terms (see also: Spanish Viceroy of Netherlands, 1540-1600s) Then again, you can see the difference between, say, the 1880s and 1920s, when airplanes became mature. Dictate by message compared to centre agents coming in to intervene directly...
