Recently got banned in a community when I brought it up, when they talked about the latter.

I'm Indian, didn't really have to read too much(on such treaties and other stuff. We do learn about the dates, major groups involved and our own people) about WW1 and WW2 before getting on the internet forums.
But how is it in Western countries?

Also, is the Bengal famine of 1943 taught?

I only got the gravity of the situation after reading about it and seeing pictures on the net.

Are there any other events that should be more known by others, in your opinion?

I hope this is not too political. If it is, do forgive me, I'll delete this.

Edit:
Recently read about the Travancore famine of 1943, that killed around 90,000 people. It happened in my state, Kerala. But I never really knew about it.
