Why was ‘lbw’ introduced in 1809?

A new method of dismissing a batsman, lbw, was introduced in 1809. Previously, as cricket uses a hard ball and leg-pads were not used, players would naturally play with their legs away from the wicket. As batsmen started to wear pads, they became willing to cover their stumps with their legs to prevent the ball hitting the stumps. Therefore a “leg before wicket” rule was introduced so that a batsman preventing the ball hitting his stumps with his legs would be out. In 1829, the length of stumps increased from 24 inches to 27 inches, and the length of the bails was increased from 7 inches to 8 inches, again to help the bowlers
