In 1914, the war in the West ground down to a stalemate. There seemed no sign that 1915 would be any different. Allied commanders experimented with new tactics to deal with this new warfare.

The beginning of 1915 sees the Central Powers under something like a giant siege. What can be done to break out?

The Great War was by no means restricted to Europe. In this episode, we begin an occasional series examining the war in Africa.

The phrase "shackled to a corpse" is often used to describe Germany's dilemma in the Great War. Surrounded by enemy nations that collectively have a greater population and larger economies, she also finds herself stuck with a disappointing alliance partner.

By the beginning of the twentieth century, the USA was the major market for Central American coffee, cotton, sugar, and especially bananas, leading to US investment in the region, leading in turn to US involvement in Central American affairs.
