Sir Henry Rider Haggard was an English writer of adventure fiction romances set in exotic locations, predominantly Africa, and a pioneer of the lost world literary genre. He was also involved in land reform throughout the British Empire. His stories, situated at the lighter end of Victorian literature and including the eighteen Allan Quatermain stories, continue to be popular and influential.

Adventure fiction is a type of fiction that usually presents danger, or gives the reader a sense of excitement. Some adventure fiction also satisfies the literary definition of romance fiction.
