Join Elizabeth McGovern as she takes an in-depth look at the young American heiresses whose real life stories inspired the acclaimed TV drama Downton Abbey. This series explores the time between the 1870s and the outbreak of World War One, when more than 200 daughters of America's new industrial millionaires marry into the money-strapped British aristocracy. They use their affluence, allure and ingenuity to their advantage, and they bring dramatic changes to the English ruling class and eventually the world.
