Beginning in 1923, some new economic rights were created for Irish citizens. The 1923 Land Act allowed the Irish Land Commission to refuse to allow a purchase of farmland by a non-Irish citizen; during the Anglo-Irish trade war the Control of Manufactures Act 1932 required that at least 50% of the ownership of Irish-registered companies had to be held by Irish citizens. “The 1932 act defined an Irish ‘national’ as a person who had been born within the boundaries of the Irish Free State or had resided in the state for five years before 1932 ... Under the terms of the Control of Manufactures Acts, all residents of Northern Ireland were deemed to be foreigners; indeed, the legislation may have been explicitly designed with this in mind.”
