A tense political game of marriage, religion, and viking invaders in eleventh century Ireland.

11th Century Ireland is awash with would-be Kings, and self-professed rulers. Real power in this land has never been more illusive.

In Brian Boru, players must marry the right bride, secure influence in the flourishing Christian Church, and repel viking invaders, all the while stealing the support of local communities away from bitter rivals. To become the King of all Ireland, you'll need to navigate a web of shifting allegiances, manage changing priorities, and ensure your many enemies do not unite against you until it's too late.
