Global Power

The Sunni and the Shia were fighting for global power. Both groups needed power to have their own way. The Sunni were generally a larger group of people, yes you may see more Shia in a country than Sunni but overall if you put them all together, the Sunni are a bigger group. 


The Sunni took up 85% of Muslims all around the world, and as a result the Sunni got their way when Abu Bakr, Muhammad's friend became the caliph.
