The dramatic history of Ireland through the 20th century is the subject of this concluding episode of Fergal Keane's series. The War of Independence in the south and the fierce resistance that ensues in the north leads to partition of the island for the first time in its history. Keane charts the developments of the two religiously dominated states , driven by big personalities like Edward Carson and Ian Paisley in the North and Eamonn de Valera and Charles Haughey in the South, up to present-day. He follows Northern Ireland's Troubles and Peace Process and the boom and bust of the Celtic Tiger years in The Republic.
