English is spoken by almost everyone in Northern Ireland. Another important language is Irish (sometimes called "Irish Gaelic") and a language known as Ulster Scots, which comes from Eastern Ulster and Lowland Scotland. The Irish language became less widely spoken in the 20th century, but a revival has led to increased usage, especially in Belfast, the Glens of Antrim and counties Tyrone and Fermanagh. This revival has been driven largely through the creation of Irish-language schools. The Irish language is spoken by some nationalists (whether Catholic or Protestant) people. Ulster Scots is almost exclusive to areas of North Antrim and the Ards Peninsula.
