Unleavened bread can refer to a wide variety of breads which are not prepared with leavening agents. Unleavened breads are generally flatbreads, however not all flatbreads are unleavened.
Unleavened breads have symbolic importance in Judaism and Christianity. Jews consume unleavened breads such as Matzo during Passover. They are also used in the Western Christian liturgy when Christians perform the Eucharist, a rite derived from the Last Supper when Jesus broke bread with his disciples during a Passover Seder. Leavened bread is used in the Eastern Orthodox Liturgy as the Body of Christ during the Eucharist.
Other unleavened breads, such as the tortilla and roti, are staple foods in Central America and South Asia, respectively.
