The usual method for widespread geographic power consolidation was to involve the whole family. From generation to generation, the bonds weakened between the branches of family established as local rulers in different areas. After a sufficient period of time, their loyalty could no longer be assured, and the taxes they collected sapped the imperial coffers. This led to situations like the reign of Emperor Wu of Han, who disenfranchised and annihilated the nobilities of virtually all imperial relatives whose forebears had been enfeoffed by his own ancestor, Gaozu.
