(beginner) History of Burundi -- "picture perfect" game

A "picture perfect" game introducing you to Burundi's main historical eras. In this game there will be four boxes -- put the events in Burundian history in chronological order. In another activity, "picture perfect game 2" there will 10 boxes and you'll get a chance to put 10 different Burundian historical periods into order.
Hint: for the final era we're going to be hopeful and hope for peace. (No one expects you to know all this off-hand -- take to the internet!)
