The Hudson’s Bay Company started out small in 1670, trading practical manufactured goods for furs with the indigenous inhabitants of inland subarctic Canada. Controlled by a handful of English aristocrats, it expanded into a powerful political force that ruled the lives of many thousands of people - from the lowlands south and west of Hudson Bay, to the tundra, the great plains, the Rocky Mountains, and the Pacific Northwest.

From 1792 to 1795, George Vancouver sailed the Pacific as the captain of his own expedition and as an agent of imperial ambition. To map a place is to control it, and Britain had its eyes on America's Pacific coast. And map it Vancouver did. His voyage was one of history's greatest feats of maritime daring, discovery, and diplomacy, and his marine survey of Hawaii and the Pacific coast was at its time the most comprehensive ever undertaken.

It was an era when monopoly trading companies were the unofficial agents of European expansion, controlling vast numbers of people and huge tracts of land, and taking on governmental and military functions. The leaders of these trading enterprises exercised virtually unaccountable, dictatorial political power over millions of people.

From the 15th to the mid-19th centuries, scurvy caused more deaths at sea than storms, shipwrecks, combat, and all other diseases combined. The cure for scurvy ranks among the greatest of military successes, yet its impact on history has mostly been ignored. In this book, Stephen R. Brown delivers a lively recounting of how three determined individuals overcame the constraints of 18th century thinking to solve the greatest medical mystery of their era. Brimming with tales of ships, sailors, and bureaucracy, Brown presents a vivid picture of life aboard the ship during the age of sail.

When Columbus triumphantly returned from America to Spain in 1493, his discoveries inflamed an already smoldering conflict between Spain's renowned monarchs, Ferdinand and Isabella, and Portugal's João II. Which nation was to control the world's oceans? To quell the argument, Pope Alexander VI issued a proclamation laying the foundation for the Treaty of Tordesillas of 1494, an edict that created an imaginary line in the Atlantic Ocean dividing the entire known (and unknown) world between Spain and Portugal.
