I need some help!

[ermm]

Hello,
I'm a 17 year-old student from Barcelona (Catalonia). I'm doing a work about minorized lenguages. I went to Scotland this summer (really beautiful), but I didn't found what I want. I have looked for some information about gaelic scottish ban.
I made an interview to some people of Bòrd na Gàidhlig, but this didn't say to me what I want

So, if you can tell me some of historical english bans to scottish gaelic I'll be really grateful.

Just say, good luck in your referendum! I think we won't have the same luck as you

Ernest.
