Although in my old age I, Allan Quatermain, have taken to writing--after a fashion--never yet have I set down a single word of the tale of my first love and of the adventures that are grouped around her beautiful and tragic history. I suppose this is because it has always seemed to me too holy and far-off a matter--as holy and far-off as is that heaven which holds the splendid spirit of Marie Marais. But now, in my age, that which was far-off draws near again; and at night, in the depths between the stars, sometimes I seem to see the opening doors through which I must pass, and leaning earthwards across their threshold, with outstretched arms and dark and dewy eyes, a shadow long forgotten by all save me--the shadow of Marie Marais.
An old man's dream, doubtless, no more. Still, I will try to set down that history which ended in so great a sacrifice, and one so worthy of record, though I hope that no human eye will read it until I also am forgotten, or, at any rate, have grown dim in the gathering mists of oblivion. And I am glad that I have waited to make this attempt, for it seems to me that only of late have I come to understand and appreciate at its true value the character of her of whom I tell, and the passionate affection which was her bounteous offering to one so utterly unworthy as myself. What have I done, I wonder, that to me should have been decreed the love of two such women as Marie and that of Stella, also now long dead, to whom alone in the world I told all her tale? I remember I feared lest she should take it ill, but this was not so. Indeed, during our brief married days, she thought and talked much of Marie, and some of her last words to me were that she was going to seek her, and that they would wait for me together in the land of love, pure and immortal....
After returning to England in 1882, Haggard published a book on the political situation in South Africa, as well as a handful of unsuccessful novels, before writing the book for which he is most famous, King Solomon's Mines. He accepted a 10% royalty rather than £100 for the copyright.
A sequel soon followed entitled Allan Quatermain, followed by She and its sequel Ayesha, swashbuckling adventure novels set in the context of the Scramble for Africa (although the action of Ayesha happens in Tibet). The hugely popular King Solomon's Mines is sometimes considered the first of the Lost World genre. She is generally considered to be one of the classics of imaginative literature. and with 83 million copies sold by 1965, it is one of the best-selling books of all time. He is also remembered for Nada the Lily (a tale of adventure among the Zulus) and the epic Viking romance, Eric Brighteyes.
His novels portray many of the stereotypes associated with colonialism, yet they are unusual for the degree of sympathy with which the native populations are portrayed. Africans often play heroic roles in the novels, although the protagonists are typically European (though not invariably). Notable examples are the heroic Zulu warrior Umslopogaas and Ignosi, the rightful king of Kukuanaland, in King Solomon's Mines. Having developed an intense mutual friendship with the three Englishmen who help him regain his throne, he accepts their advice and abolishes witch-hunts and arbitrary capital punishment.
Three of Haggard's novels were written in collaboration with his friend Andrew Lang who shared his interest in the spiritual realm and paranormal phenomena.
Haggard also wrote about agricultural and social reform, in part inspired by his experiences in Africa, but also based on what he saw in Europe. At the end of his life, he was a staunch opponent of Bolshevism, a position that he shared with his friend Rudyard Kipling. The two had bonded upon Kipling's arrival at London in 1889 largely on the strength of their shared opinions, and the two remained lifelong friends.
