Dukedom is a turn-based strategy text-based video game about land management and was created as an expanded version of Hamurabi.

The player is one of several Dukes chosen by the High King to help run the Kingdom.

Their Duchy is not in the best of shape, the gameplay goal is to build up its population, land holdings, and grain reserves, ultimately hoping to become powerful enough to overthrow the High King.

The player has to manage their duchy, while paying taxes and sending, on occasion, peasants to the King's service, undergoing epidemics, locusts and rival lords secretly helped by the High King; they can buy and sell land, itself divided in several categories depending on fertility, and engaging in offensive or defensive warfare, sending both subjects and mercenaries against the enemy and winning land and grain.

[citation needed] The game was converted to Microsoft BASIC by Richard A. Kaapke.
