50 free Vietnam trivia questions with answers — geography quiz, new questions added Aug 2026.
45 free Vietnam trivia questions with answers. Vietnam trivia in three parts. First the country: where it sits, its capital and largest city, the Mekong and Red River deltas, Fansipan, Ha Long Bay's descending dragon and the cave big enough to hold a skyscraper. Then the history: a thousand years of Chinese rule, Ngo Quyen at Bach Dang, three Mongol invasions repelled, French Indochina, Dien Bien Phu, the Geneva partition, Diem, the Gulf of Tonkin, Tet, My Lai, the Paris Accords, the fall of Saigon and the Doi Moi reforms that followed. Finally the culture: pho and banh mi, the ao dai, robusta coffee, Tet, the national football team and the woman who wrote Vietnam's most famous poem. The Vietnam War trivia sits inside the same set rather than on a separate page, so a searcher gets the whole picture: dates, turning points, casualties and the peace deal whose Nobel Prize one negotiator refused. Easy questions open the quiz; the later ones will test a history graduate. Every answer has been checked against a reference page and each question shows its citation.
