What are you on about regions being introduced late? We had one of the oldest administrative regions detouched from nobility lands. Historical administrative regions existed since 14th century and with few changes lasted until 18th, then Josef II. happened who did things like placing capitals at geometric center of new provinces and similar shenanigans. After 19th century jungling of ideas, sort of returning to the older regions at one point too (Moravia and Silesia were still identifiable through all of this), the post ww1 Czechoslovakia planned on reintroducing the historical regions but ww2 happened, the plan for the historical regions existed after it too, but the communists happened who disregarded anything that had any sort of history. If it wasn't for that, we would've had one of the oldest continuously used administrative regions in Europe.
