Poldark is a series of historical novels by Winston Graham. They have been adapted to the television screen twice by the BBC, with Poldark airing in 1975 and 1977 and a new version, also called Poldark, beginning in 2015.
The main character, Ross Poldark, a British Army officer, returns to his home in Cornwall from the American Revolutionary War only to find that his fiancée, Elizabeth Chynoweth, having believed him dead, is about to marry his cousin, Francis Poldark. Ross attempts to restore his own fortunes by reopening one of the family’s tin mines. After several years he marries Demelza Carne, a servant girl, and is gradually reconciled to the loss of Elizabeth’s love. By then, Elizabeth has become a widow and marries George Warleggan, Ross’s arch-enemy.
There are a total of twelve novels. The first seven novels are set in the 18th century, until Christmas 1799. The remaining five are concerned with the early years of the 19th century and the lives of the children of the main characters of the previous novels. Winston Graham wrote the first four Poldark books during the 1940s and 1950s. Following a long hiatus, he decided to resume the series, and The Black Moon was published in 1973.
