Remnants of one of the oldest surviving Passover haggadahs in the world, which was discovered in the Cairo Genizah, are currently on display as part of an exhibit at the National Library of Israel in Jerusalem. The haggadah, hand-scribed on parchment, dates from the 12th century CE.

Although we should not abandon even the most seemingly insignificant customs of the Seder, it is appropriate to emphasize rituals that are absolutely required.

There are 5 mitzvot (commandments) that every Jew must perform at the Seder. Two are biblical in origin, and three are mandated by the rabbis.
