Thirty years ago Portugal was freed from dictatorship in an almost bloodless coup.
But beneath the euphoria of the 'Revolution of the Carnations', lies the more troubled story of the wars in its former colonies - Angola, Mozambique and Guinea Bissau - that prompted the apparently peaceful coup and followed in its wake.
In Lisbon, James Maw tries to find out what happened when the Empire sailed back home and how Portugal and its former colonies have been transformed by the aftermath of the Revolution.
For sixty years, Inger Stridsklev has been beaten and spat upon and asked to deny the truth about her birth.
Inger and many like her have been victimised because their parents were members of Norway's wartime collaborationist government.
Is it possible that the most basic of human rights is still being denied them?
When the much-decorated war hero General Paul Aussaresses admitted torturing and killing the enemies of France in the Algerian War, he caused a national scandal.
James Maw asks whether the French have come to terms with their country's role in Algeria; and he meets the Harkis, a little-known group of Algerian soldiers who fought with the French - shunned by their native land and seemingly forgotten by France itself.
In the spring of 1948, 28,000 children walked across the mountains of Northern Greece into Albania, Yugoslavia and Bulgaria.
They expected to return to their villages within weeks or months, but many found themselves locked out of their homeland for decades.
In this final programme in the series, James travels from Athens to Skopje, talking to those whose lives were changed forever by the bitter divisions of the Greek Civil War.
