If you were wondering what happened to equestria in the 1940s, It was rather Mortifying. Equestria was at War with Nazi Germaneigh. Here is what the main characters ancestors were in World War II.

A Division of the R.A.F, Because of this, he immediately was an Alicorn, He invested Billion of bits when funding the R.A.F.

Pinkie Pie was a member of the army. and became mentally insane after killing 40,000 germans. She was deemed unsafe for the military, so she joined Mr and Mrs Cake, Who had recently had 2 children.
