What happened in 1215 to give the people of england more rights?

the conditions that made the byzantine empire vulnerable to attacks by the muslin turks were the sack of constantinople by western crusaders, the conquests of the sultanate of rum, presence of rival kingdoms and finally the set up of fiefdoms at the empire which were owned by the ghazis (turkish warriors).

the supreme court can hear any case it wishes as long as four justices agree to hear it.

hope this , give me brainliest answer =j
