King's Solomon's Mines is an adventure novel by H. Rider Haggard, first published in 1885. It tells of a group of Englishmen who travel into Darkest Africa in search of the legendary diamond mines of The Bible's King Solomon. It was enormously successful, launching the Jungle Opera genre, and was followed by over a dozen sequels and prequels featuring the protagonist Allan Quatermain, including a crossover with Haggard's other most famous novel, She. It has been adapted for film and television many times.
