Andrew Carnegie: Rags to Riches, Power to Peace charts the story of a poor Scottish immigrant who sailed to America in the 1840s, and by the end of the century would be the richest man in the world.

Criticised for the harsh business practices that allowed him to dominate the iron and steel industries, and praised for his quest to give all his money away, Andrew Carnegie is undeniably one of the most fascinating and contradictory figures in modern history.

His name is synonymous with the modern philanthropic movement, and the libraries and educational institutions he established thrive almost a century after his death.

From his Scottish highland retreat, Skibo Castle, Carnegie spent his retirement masterminding a plan to use his wealth and influence to get Theodore Roosevelt, Kaiser Wilhelm II and King Edward VII to create a framework for world peace in the run up to the Great War.

This documentary reveals the untold story of a man with incredible vision, whose dream of a world without conflict ended in tatters and led him to die a broken man.
