Las Posadas is the Mexican celebration that reenacts Mary and Joseph’s search for shelter from December 16 to 24.
The name comes from the Spanish word posada, meaning lodging or accommodation. During the nine-night observance, processions or gatherings dramatize the couple’s journey to Bethlehem. Participants sing alternating verses requesting and granting shelter, then continue with prayers, food, music and community celebration.
The nine days are commonly linked symbolically with Mary’s nine months of pregnancy. In Mexico, the tradition developed from Catholic Christmas observances established in the sixteenth century, including the misas de aguinaldo associated with Augustinian friars at Acolman near Mexico City. Over time, local customs such as piñatas, candles, sweets and ponche became part of the festivities.
Las Posadas is not the same as Día de los Muertos, which honors deceased loved ones, or Cinco de Mayo, which commemorates the Battle of Puebla. A related nine-day observance in parts of South America is called Novena de Aguinaldos.
