The dramatic story of Christianity from its origins to the present day, told through more than one hundred stunning color maps. With over two billion practicing believers today, Christianity has taken root in almost all parts of the globe. Its impact on Europe and the Americas in particular has been fundamental. Through more than one hundred beautiful color maps and illustrations, Christianity traces the history of the religion, beginning with the world of Jesus Christ. From the consolidation of the first Christian empire-Constantine's Rome-to the early Christian states that thrived in Ireland, Ethiopia, and other regions of the Roman periphery, Christianity quickly proved dynamic and adaptable. After centuries of dissemination, strife, dogmatic division, and warfare in its European and Near Eastern heartland, Christianity conquered new worlds. In North America, immigrants fleeing persecution and intolerance rejected the established Church, and in time revivalist religions flourished and spread. Missionaries took the Christian message to Latin America, Africa, and Asia, bringing millions of new converts into the fold. Christianity has served as the inspiration for some of the world's finest monuments, literature, art, and architecture, while also playing a major role in world politics and history, including conquest, colonization, conflict, and liberation. Despite challenges in the modern world from atheism and secularism, from scandals and internal divisions, Christianity continues to spread its message through new technologies while drawing on a deep well of history and tradition.

No single human invention has changed the nature of war more that the development of the aeroplane. The History of Air Warfare is a highly illustrated and accessible account of the development of aerial warfare, from the first skirmishes over the Western Front in World War I to today's hi-tech netcentric aerial battlespace. Developing from unpowered observation hot air balloons in the 18th century and even the older kite, aerial warfare has become a multibillion-dollar industry and has led to many advances in technology and techniques such as aerodynamics, propulsion, radar and use of composites and engineered materials such as carbon fibre. Featuring more than 120 complex computer-generated battle maps and graphics, the History of Air Warfare explores every major air battle to have taken place in the world's skies, as well as documenting the air element of campaigns such as Operation Barbarossa and Operation Desert Storm. Extensively researched text tells the history and the stories behind these battles concisely and clearly.
