I am from/in Mexico and , to our shame and demerit, we failed to provide sanctuary to Trotsky after he was exiled by Joseph Stalin's forces in Soviet Russia.
Now, I understand that Mexico was sympathetic to communism and spceifically sympathetic to Trotsky, believe you me, I know this very well.
My question is, out of all the places in the world, why specifically Mexico? it does not appear he had been here before, nor that he had major dealings with any of the prominent figures at the time, so I am left a bit confused as to why this was his choice.
/u/Cozijo answered this question posited slightly differently (as in, why did the Mexican government offer Trotsky asylum and what was the history of Russian Socialist influence in Mexico) here a couple of years ago. You might find their response informative.
