In 55 and 54 BC, Julius Caesar landed in the south of the island of Britain, then known as Britannia. This was the first contact between Rome and the various British kingdoms. Numerous kings rallied to Caesar to survive, or to benefit from Rome's protection against the hostility of other British tribes: these were the first client kingdoms. This system would develop over the next century, so that by the time of Claudius' Roman invasion in AD 43, many client kingdoms were already well established.
Among these were the Regnenses, Brigantes and Iceni, who fought mercilessly for power. With Rome's support, they all tried to obtain the title of King of the British, in Latin: REX BRITANNORUM.
Rex Britannorum is a strategy game that can be played solo, with 2 or 3 players. Victory is achieved by occupying roads and cities in the different regions of Britannia displayed on the game board. Moreover, each player will have two personal objectives to complete, which will earn them additional victory points.
Commit your troops in the right place and at the right time to outplay your opponents. Resolution of battles is not random, so use your sense of strategy wisely to become the Rex Britannorum.
