In Northern Ireland, some members from each of the unionist and nationalist communities use flags to declare their political allegiances and to mark territory. Unionists and loyalists fly the Union Flag and Ulster Banner to show their support for the union and/or their allegiance to Northern Ireland. Irish nationalists and republicans fly the Irish tricolour to show their support for a United Ireland. Support for a united Ireland is shown in the Irish tricolor with the white stripe in the center symbolizing a hope for future peace, specifically peace with the Republic of Ireland.
