Lord Acton (1834-1902), numbered among the most esteemed Victorian historical thinkers, was much respected for his vast learning, his ideas on politics and religion, and his lifelong preoccupation with human freedom. Yet Acton was in many ways an outsider. He stood apart from his contemporaries, doubting the notion of unlimited progress and the blessings of nationalism and democracy. He differed from fellow members of the English upper class, holding to his Catholic faith. And he angered other Catholic believers by fiercely opposing the doctrine of papal infallibility. In this remarkable biography, Roland Hill is the first to make full use of the vast collection of books, documents, and private papers in the Acton archives to tell the story of the enigmatic Lord Acton. The book describes Acton's extended family of European aristocrats, his cosmopolitan upbringing, and his disrupted education. Drawing a lively picture of politics and religion at the time, Hill discusses Acton's brief career as a Liberal member of Parliament, his work as editor and owner of learned Catholic journals, his battles for freedom for and in the Catholic Church, his friendship with William E. Gladstone, and his seven years as Regius Professor of Modern History at Cambridge University. Though unable to complete The Cambridge Modern History series he envisaged, Acton transformed historical study and left a legacy of ideas that continues to influence historians today.

Lord Acton (1834-1902) and Richard Simpson (1820-76) were the principal figures in the Liberal Catholic movement of nineteenth-century England, an ultimately unsuccessful effort to reconcile the Roman Catholic Church with the leading secular thought of the day. They collaborated in editing the Rambler (1858-62) and the Home and Foreign Review (1862-4), two of the most distinguished Catholic periodicals of the period. The correspondence is the record of this collaboration and sheds light on the religious, political and intellectual history of mid-nineteenth-century England. Though heaviest for the years of their joint work on the Rambler and the Home and Foreign Review, the correspondence continued up to 1875, a year before Simpson's death.

Lord Acton (1834–1902) is often called a historian of liberty. A great historian and political thinker, he had a rare talent to reach beneath the surface and reveal the hidden springs that move the world. While endeavoring to understand the components of a truly free society, Acton attempted to see how the principles of self-determination and freedom worked in practice, from antiquity to his own time. But though he penned hundreds of papers, essays, reviews, letters and ephemera, the ultimate book of his findings and views on the history of liberty remained unwritten. Reading a book a day for years he still could not keep pace with the output of his time, and finally, dejected, he gave up. Today, Acton is mainly known for a single maxim, power tends to corrupt, and absolute power corrupts absolutely. In Power Tends to Corrupt, Christopher Lazarski presents the first in-depth consideration of Acton's thought in more than fifty years. Lazarski brings Acton's work to light in accessible language, with a focus on his understanding of liberty and its development in Western history. A work akin to Acton's overall account of the history of liberty, with a secondary look at his political theory, this book is an outstanding exegesis of the theories and findings of one of the nineteenth century's keenest minds.

New attitudes towards history in nineteenth-century Britain saw a rejection of romantic, literary techniques in favour of a professionalized, scientific methodology. The development of history as a scientific discipline was undertaken by several key historians of the Victorian period, influenced by German scientific history and British natural philosophy. This study examines parallels between the professionalization of both history and science at the time, which have previously been overlooked. Hesketh challenges accepted notions of a single scientific approach to history. Instead, he draws on a variety of sources—monographs, lectures, correspondence—from eminent Victorian historians to uncover numerous competing discourses.
