The Crusades had a wide variety of impacts on societies throughout Europe, Asia, and Africa. One such notable impact was its role in the development of knowledge between cultures. This book argues that the Nubian kingdom of Dotawo and the Latin Christians became increasingly more connected between the twelfth and early fourteenth centuries than has been acknowledged. Subsequently, when Solomonic Ethiopian-Latin Christian diplomatic relations began in 1402, they were building on the prior connections of Nubia, either wittingly or unwittingly: Ethiopia became the 'Ethiopia' that the Latin Christians had previously been aiming to develop relations with. The histories of Nubia, Ethiopia, and the Crusades were directly and indirectly entwined between the twelfth century and 1402. By placing Nubia and Ethiopia within the wider context of the Crusades, new perspectives can be made regarding the international activity of Nubia and Ethiopia between the twelfth and fifteenth centuries and the regional role reversal of Dotawo and Solomonic Ethiopia from the early fourteenth century. Prior to the fourteenth century, Nubia had been the dominant Christian power in the region before Solomonic Ethiopia began to replace it, including by adopting elements of discourse which had previously been attributed to Nubia, such as its ruler being the recognised protector of the Christians of north-east Africa. This process should not be viewed in isolation of the wider regional geo-political context. Nubia, Ethiopia, and the Crusading World, 1095-1402 will appeal to all those interested in the history of the Crusades, Nubia, and Ethiopia, particularly concerning inter-regional physical and intellectual connectivity.

This is a fascinating encyclopedia comparing the most important adaptations and evolutions in the natural world with the most important discoveries and inventions of human history. Welcome to the amazing world of adaptations, where species-including humans-develop fascinating new capabilities to ensure a competitive edge in their environment, or in some cases, survival itself. Encyclopedia of Adaptations in the Natural World is a wide-ranging catalog of the most important of those adaptations-from photosynthesis to the the peculiar "vampire"-like behavior of the tiny life form called the prion. The seven chapters in the Encyclopedia cover the key survival challenges all organisms face. Entries within those chapters cover specific adaptations from all forms of life, including animals, plants, bacteria, algae, fungi, and viruses. For each adaptation, the book also describes a related technological breakthrough in the human world, showing how engineers today study natural processes to help them develop new inventions. Provides diagrams of the process of photosynthesis, the functional areas of the human brain, and the bluefin tuna Includes 58 photographs and electron microscope images illustrating the adaptations in the book Presents bibliographic listings of key reference books, internet resources, and academic papers for further reading
