Aristotle Onassis is the correct answer.
Border ruffians contributed to the "bleeding Kansas" problem by actively terrorizing citizens of the free state. The Border ruffians came from the slave state of Missouri and in an attempt to change attitudes through force, they would actively terrorize opponents to their pro-slavery stance. The "bleeding Kansas" problem occurred as is was decided around the time of 1950 that the settlers themselves would choose whether Kansas was a free or slave state. This resulted in a flood of people from both sides rushing to settle Kansas in order to gain another state that aligned with their particular values. The period lasted until about 1959-60 and animosity persisted through the civil war.
In my opinion, the greatest accomplishment that the Roman civilization did was conquering land. The Roman's were very skilled when it comes to getting more land for their empire, and that's what they did. Because of how successful and powerful their military was, they conquered land that was already owned by other empire's. The Roman's conquered land from empire's like he Celtic tribes, Carthage, the Hellenistic Empires, and many more. They conquered a large amount of Europe, North Africa, and Western Asia. This makes it a very big accomplishment because no other Empire had the manpower that the Roman's had, and because of Rome's manpower, they were bound to conquer a lot of Europe and other land. Them expanding their empire allowed them to control most of Europe and other places.
