The ‘March Madness series of North American College basketball games uses a ‘bracket’ system to eliminate teams. You can use the same bracket system to run a series of debates or individual considerations to identify the most significant / important cause of an historical event.

Begin by identifying 8 key factors, which are written on the 8 legs of the 1st Round. Each pair of factors is debated, with the ‘winner’ (i.e. the most convincing argument) making it through to the 2nd Round. The 2nd Round factors are then debated against each other, resulting in the final two factors making it through the the Championship round.
