India is the biggest democracy in the world. Bangladesh was a functional democracy for a good stretch until last year. At least on paper, Afghanistan and Iraq were democracies.
Afghanistan was almost never a democracy tho. It was mostly monarchies until 1973.. then a totalitarian state from 1978-ish until 1989… then mostly in civil war until 1996.. when it was again mostly a totalitarian state.. then it got invaded by the US in 2001.. until 2021 when it got again under a totalitarian state.
