Q. Which of the following country was officially declared to be the world’s first atheist state after world war II?
Answer: Albania
Notes: In 1967 Enver Hoxha, the head of state of Albania, declared Albania to be the "first atheist state of the world" even though the Soviet Union under Lenin had already been a de facto atheist state.[ Marxist–Leninist authorities in Albania claimed that religion was foreign to Albania and used this to justify their policy of state atheism and suppression of religion.
