Imperialism, sometimes called the Imperialist Movement, was a phenomenon wherein empires sought to expand and gain more land, often violently.

Notable examples include the Ochebanian Deltree Dynasty's imperialist expansion into the Colupan Archipelago, post-Orc Wars Denisite expansion towards Bao-Mou, Twinisle, and Bamea, and the Holy Dwarven Empire's invasion of most of Ochebana.

Variations

The most common application of imperialism was violent expansion into neighboring territory, with justified claims or without.

A second method, called federalist rather than expansionist, was the forced or encouraged the incorporation of states into an empire, without waging war or removing the attached territory's autonomy. Many federations, including Denise's Phoenix mentioned above, utilized this second method to expand.
