Hans Baron was one of the many great German émigré scholars whose work Princeton brought into the Anglo-American world. His Crisis of the Early Italian Renaissance has provoked more discussion and inspired more research than any other twentieth-century study of the Italian Renaissance. Baron's book was the first historical synthesis of politics and humanism at that momentous critical juncture when Italy passed from medievalism to the thought of the Renaissance. Baron, unlike his peers, married culture and politics; he contended that to truly understand the Renaissance one must understand the rise of humanism within the political context of the day. This marked a significant departure for the field and one that changed the direction of Renaissance studies. Moreover, Baron's book was one of the first major attempts of any sort to ground intellectual history in a fully realized historical context and thus stands at the very origins of the interdisciplinary approach that is now the core of Renaissance studies. Baron's analysis of the forces that changed life and thought in fifteenth-century Italy was widely reviewed domestically and internationally, and scholars quickly noted that the book "will henceforth be the starting point for any general discussion of the early Renaissance." The Times Literary Supplement called it "a model of the kind of intensive study on which all understanding of cultural process must rest." First published in 1955 in two volumes, the work was reissued in a one-volume Princeton edition in 1966.

The evolution of republican concepts compared to medieval and early modern traditions of political thought.

Hans Baron's Crisis of the Early Italian Renaissance is widely considered one of the most important works in Italian Renaissance studies. Princeton University Press published this seminal book in 1955. Now the Press makes available a two-volume collection of eighteen of Professor Baron's essays, most of them thoroughly revised, unpublished, or presented in English for the first time. Spanning the larger part of his career, they provide a continuation of, and complement to, the earlier book. The essays demonstrate that, contemporaneously with the revolution in art, modern humanistic thought developed in the city-state climate of early Renaissance Florence to a far greater extent than has generally been assumed. The publication of these volumes is a major scholarly event: a reinforcement and amplification of the author's conception of civic Humanism. The book includes studies of medieval antecedents and special studies of Petrarch, Leonardo Bruni, and Leon Battista Alberti. It offers a thoroughly re-conceived profile of Machiavelli, drawn against the background of civic Humanism, as well as essays presenting evidence that French and English Humanism of the sixteenth and seventeenth centuries was closely tied to Italian civic thought of the fifteenth. The work culminates in a reassessment of Jacob Burckhardt's pioneering thought on the Renaissance. Originally published in 1988. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The Intellectual Struggle for Florence is an analysis of the ideology that developed in Florence with the rise of the Medici, during the early fifteenth century, the period long recognized as the most formative of the early Renaissance. Instead of simply describing early Renaissance ideas, this volume attempts to relate these ideas to specific social and political conflicts of the fifteenth century, and specifically to the development of the Medici regime. It first shows how the Medici party came to be viewed as fundamentally different from their opponents, the 'oligarchs', then explores the intellectual world of these oligarchs (the 'traditional culture'). As political conflicts sharpened, some humanists (Leonardo Bruni and Francesco Filelfo) with close ties to oligarchy still attempted to enrich traditional culture with classical learning, while others, such as Niccolò Niccoli and Poggio Bracciolini, rejected tradition outright and created a new ideology for the Medici party. What is striking is the extent to which Niccoli and Poggio were able to turn a Latin or classical culture into a 'popular culture', and how the culture of the vernacular remained traditional and oligarchic.
