Explain de facto sovereignty?

De facto sovereignty refers to a situation where a government or authority effectively controls a territory and exercises the functions of a sovereign state, even if it does not have legal recognition or legitimacy. This can occur in cases where a government has seized power through force or other means, or where a government is not recognized by the international community. De facto sovereignty can be temporary or long-term, and may eventually lead to de jure sovereignty if the government gains legal recognition.
