When did the football start?

According to historical reports, there is said to be having similarities between Rugby and Football in the way that both the games include running to the end line to score. There is also reports saying that in the 1820's, Princeton students played something like that. The rules consisted of using the hand or feet to carry the ball to the opposing goal. Also later in 1860, there are records of students in Harvard playing the game similarly. When Harvard began playing football, it was known to be caled "Bloody Monday". It earned the name because it was played on the said date and was very physical.
