Vietnam has never had a democratic government, so nothing has ever happened to this non-existent entity. If you are referring to the Republic of Vietnam (often called South Vietnam), which was a regime in the south of Vietnam from 1954-1975, this country was not a democracy. Although it has the word "Republic" in its name, it was really a state ruled by a strongman who was deeply beholden to US interests. As for what happened to this country, when the US withdrew military forces from Vietnam in 1973, the North Vietnamese Army overran the defenses of South Vietnam and conquered the country, bringing Vietnam into united Communist rule.
