In 1864, amid headline-grabbing heresy trials, members of the British Association for the Advancement of Science were asked to sign a declaration affirming that science and scripture were in agreement. Many criticized the new test of orthodoxy; nine decided that collaborative action was required. The X Club tells their story.

These six ambitious professionals and three wealthy amateurs—J. D. Hooker, T. H. Huxley, John Tyndall, John Lubbock, William Spottiswoode, Edward Frankland, George Busk, T. A. Hirst, and Herbert Spencer—wanted to guide the development of science and public opinion on issues where science impinged on daily life, religious belief, and politics. They formed a private dining club, which they named the X Club, to discuss and further their plans. As Ruth Barton shows, they had a clear objective: they wanted to promote “scientific habits of mind,” which they sought to do through lectures, journalism, and science education. They devoted enormous effort to the expansion of science education, with real, but mixed, success. 

​For twenty years, the X Club was the most powerful network in Victorian science—the men succeeded each other in the presidency of the Royal Society for a dozen years. Barton’s group biography traces the roots of their success and the lasting effects of their championing of science against those who attempted to limit or control it, along the way shedding light on the social organization of science, the interactions of science and the state, and the places of science and scientific men in elite culture in the Victorian era.

Today, foreigners travel to the Yucatan for ruins, temples, and pyramids, white sand beaches and clear blue water. One hundred years ago, they went for cheap labor, an abundance of land, and the opportunity to make a fortune exporting cattle, henequen fiber, sugarcane, or rum. Sometimes they found death.

In 1875 an American plantation manager named Robert Stephens and a number of his workers were murdered by a band of Maya rebels. To this day, no one knows why. Was it the result of feuding between aristocratic families for greater power and wealth? Was it the foreseeable consequence of years of oppression and abuse of Maya plantation workers? Was a rebel leader seeking money and fame—or perhaps retribution for the loss of the woman he loved?

For whites, the events that took place at Xuxub, Stephens’s plantation, are virtually unknown, even though they engendered a diplomatic and legal dispute that vexed Mexican-U.S. relations for over six decades. The construction of "official" histories allowed the very name of Xuxub to die, much as the plantation itself was subsumed by the jungle. For the Maya, however, what happened at Xuxub is more than a story they pass down through generations—it is a defining moment in how they see themselves.

Sullivan masterfully weaves the intricately tangled threads of this story into a fascinating account of human accomplishments and failings, in which good and evil are never quite what they seem at first, and truth proves to be elusive. Xuxub Must Die seeks not only to fathom a mystery, but also to explore the nature of guilt, blame, and understanding.
