Definition
一统天下 is a four-character idiom meaning 'to unify the whole country under one rule.' It originates from ancient Chinese history, where a ruler would bring all warring states under a single dynasty. In modern usage, it can also be used metaphorically to mean 'to dominate or achieve complete control' in a given field or context. As a separable verb-object phrase (v.o.), the components can be separated: 统天下 without 一 — though the full form is more common.
v.o.
