Poldark is a television drama based on Winston Graham's novels of the same title. It was first transmitted on BBC Two across two seasons between 1975 and 1977. The adaptation covered all seven novels (of the eventual twelve) published up to the time. In late 18th-century Cornwall, Ross Poldark loses his fiancée, well-bred beauty Elizabeth, to his cousin Francis. He ends up marrying his servant, Demelza Carne, but his passion for Elizabeth simmers on for years. Meanwhile, he strives to make his derelict copper mines a success. Life is hard, smuggling is rife, and Ross finds himself taking the side of the underclass against the ruthless behaviour of his enemies, the greedy Warleggan clan.
