The Unrestricted submarine warfare was effecting the lives of Americans traveling across seas, one example is the sinking of the RMS Lusitania. Which some of the passangers were Americans.

The intolerable law were five laws against american colonist by the british in 1774 as punishment for the boston tea party. So the colonist voiced their opposition on a local level.
