jan 10, 49 BC - Crossing the Rubicon
Description:
Caesar crossed the Rubicon River, the boundary between the province of Cisalpine Gaul to the north and Italy proper to the south. As crossing the Rubicon with an army was prohibited, lest a returning general attempt a coup d'etat, this triggered the ensuing civil war between Caesar and Pompey.
