The Putzger - Historischer Weltatlas is one of the most authoritative and long-standing historical atlases in Europe, continuously revised since the nineteenth century. This expanded 103rd edition combines detailed historical cartography with explanatory texts, diagrams and thematic overviews. Covering global history from ancient civilizations to the early twenty-first century, the atlas offers a comprehensive visual representation of political developments, cultural transformations, economic systems and demographic change. Designed for both educational and reference use, it serves students, teachers and historians as a reliable tool for understanding spatial and historical processes. The atlas is organized chronologically and thematically. Early sections focus on ancient civilizations and the spatial development of early states, followed by extensive coverage of medieval Europe, early modern empires, colonial expansion and modern global history. Each map is accompanied by contextual texts, timelines, tables and graphical elements that explain historical dynamics such as trade networks, population movements, warfare and technological progress. A comprehensive index containing several thousand geographical and historical entries allows for precise consultation, making the work both a visual atlas and a structured reference tool. Ernst Bruckmuller and Peter Claus Hartmann are German historians specializing in modern European history and historical cartography. As long-time editors of the Putzger atlas series, they have overseen its modernization by integrating updated historical research, didactic clarity and contemporary cartographic standards. They collaborated with a multidisciplinary team of historians and geographers who contributed specialized expertise in regional history, spatial analysis and educational mapping. Their editorial work has ensured the continued academic relevance of the Putzger atlas in schools and universities.
