In 57 BC Julius Caesar conquered Gaul and also Belgica (modern day Northern France, Belgium and a southern section of the Netherlands to the Rhine River; and the north-western portion of North Rhine-Westfalia, Germany.) There were several tribes in the country who fought against each other regularly. The Eburones were ruled by Ambiorix and Catuvolcus. In 54 BC Caesar's troops urgently needed more food and thereby the local tribes were forced to give up part of their harvest, which had not been good that year. Understandably the starving Eburones were reluctant to do so and Caesar ordered that camps be built near the Eburones' villages. Each centurion was ordered to make sure the food supplies were delivered to the Roman soldiers. This created resentment among the Eburones.
