Some people in specific countries are not keen on learning English... 'specific' sounds wrong to me as you don't specify them- you could try 'certain'.
a mean - wrong form
English came across - why the past?
of the English spread - reorder
countries, which - punctuation
direct involvement in major historical facts- not natural phrasing
put into that British, Australian and so on- change verb
It was a kind of friendly invasion, new music was welcome by the youth, it was like the opportunity of breathing new hope.- pubctuation + look the last phrase
that took part of the country- change verb
English speakers of spreading - preposition and verb form
