Imperialism is a turn-based strategy game for Microsoft Windows and Apple Macintosh computers, developed by Frog City Software and published by Strategic Simulations in 1997.

In the first case, the player selects one of seven "great powers" and starts ruling in 1815, a year considered by many historians the beginning of the 19th-century era in the real world.

In either case, the empire must have a solid economic grounding, which is established by the exploitation of the country's resources (wood, ore, etc.

In the historical scenarios, the player chooses a European power - available are Great Britain, France, Austria-Hungary, the Ottoman Empire, Russia, and, depending on the period chosen, Prussia and Sardinia, or respectively Germany and Italy.

Research can allow increased production of some raw materials, or allow for military upgrades, or in some cases render parts of the navy fleet obsolete.

Lumber can be used to expand internal transport, to increase factory output, or for producing merchant ships and warships.

Timber can also be processed into paper, which is used to train workers for higher levels of productivity, and then educate them so that they can serve in more advanced military units.

Paper is also necessary to train expert workers as specialists (i.e. prospectors, engineers, miners, ranchers, farmers, foresters and oil drillers).

The money required to build Trade Consulates and Embassies is significant, especially early in the game, when the player's revenue is limited.

[2] According to former members of Frog City Software at Sidecar Studios, Imperialism's commercial performance was unexpectedly strong.
