History, 400-1000
Celtic Christianity came into North Britain sometime between 200 and 400 AD; it came from Ireland and with the Scoti, who established the kingdom of Dalriada spanning the southwest of Scotland and the northeast of Ireland. This invasion angered and provoked the Picts, who fiercely resisted these new people from the west. But the Picts faced as well invaders from the south, and the two forces often proved too much for the native folk. By 1000, the Picts and the Scots had begun to blend together to form a Celtic and Celtic Christian kingdom upon the old Pictish-Scottish base.
