After the tenth plague Pharaoh finally agreed to let the Jewish People leave Egypt.  The Jewish People had to make hurried preparations as Pharaoh's heart could harden again and he could change his mind.  The Jewish People attempted to bake bread for the journey but the dough did not have time to rise and the bread came out of the ovens as unleavened or matzah.  It is because of this that the Jewish People are commanded to observe Passover by eating only unleavened bread during the eight days of Passover.
