This book is concerned with the machinery of medieval siegecraft as used by Chinese, Mongol, Japanese and Korean armies. Almost all the machinery was initially developed in China, but each country provides its own context into which the siege engines were fitted, and distinctive differences reveal both strengths and weaknesses in the machines themselves, and also raise questions about cultural attitudes to siegecraft and even to the practise of war itself. This, the first volume, deals with the machinery of siege warfare prior to the introduction of gunpowder (though some earlier incendiary weapons are considered).

The Modern World, Volume 3: Civilizations of the AmericasThe countries that occupy the continents of North America and South America have unique histories. Europeans colonized areas that had been occupied for thousands of years by diverse societies and cultures, which, in turn, gave way to an array of countries with their own specific historical development.
Those who followed Columbus were called conquistadors, or conquerors. In 1521, Hernán Cortés and his men subjugated the Aztecs of present-day Mexico, who were already weakened by civil war. Francisco Pizarro soon oversaw the dismantling of the Incan Empire in South America...
