50 free Republic of the Congo trivia questions with answers — geography quiz, new questions added Aug 2026.
This Republic of the Congo trivia quiz is about Congo-Brazzaville, the smaller of the two Congos, and only the smaller one: its capital facing Kinshasa across the river, the Italian-born explorer who founded it, its stint as the capital of Free France, its years as Africa's first Marxist-Leninist people's republic, and its oil, its swamp-forest gorillas and its impeccably dressed sapeurs. The early questions cover the map and the flag; the later ones get into Tio kings, the Congo-Ocean Railway, Marien Ngouabi and the 1972 Africa Cup of Nations. Every question is multiple choice with a short explanation after you answer. If you want the Democratic Republic of the Congo, that is a separate quiz. Every answer has been checked against a primary source, and each question links to the page that confirms it.
