Palm Sunday is a Christian moveable feast that falls on the Sunday before Easter. The feast commemorates Jesus' triumphal entry into Jerusalem, an event mentioned in all four canonical Gospels.

In many Christian churches, Palm Sunday includes a procession of the assembled worshipers carrying palms, representing the palm branches the crowd scattered in front of Jesus as he rode into Jerusalem. The difficulty of procuring palms in unfavorable climates led to their substitution with branches of native trees, including box, yew, willow, and olive. The Sunday was often designated by the names of these trees, as in Yew Sunday, or by the general term Branch Sunday



Biblical basis and symbolism

In the accounts of the four canonical Gospels, Jesus' triumphal entry into Jerusalem takes place about a week before his Resurrection.
The symbolism is captured in Zechariah 9:9 "The Coming of Zion's King – See, your king comes to you, righteous and victorious, lowly and riding on a donkey, on a colt, the foal of a donkey". It was perceived that Jesus was declaring he was the King of Israel to the anger of the Sanhedrin.

According to the Gospels, Jesus rode a donkey into Jerusalem, and the celebrating people there laid down their cloaks in front of him, and also laid down small branches of trees. The people sang part of Psalm 118: 25–26 – ... Blessed is He who comes in the name of the Lord. We bless you from the house of the Lord ...
The symbolism of the donkey may refer to the Eastern tradition that it is an animal of peace, versus the horse, which is the animal of war. A king came riding upon a horse when he was bent on war and rode upon a donkey when he wanted to point out he was coming in peace. Jesus' entry to Jerusalem would thus symbolize his entry as the Prince of Peace, not as a war-waging king. In Luke 19:41 as Jesus approaches Jerusalem, he looks at the city and weeps over it (an event known as Flevit super illam in Latin), foretelling the suffering that awaits the city.

In many lands in the ancient Near East, it was customary to cover in some way the path of someone thought worthy of the highest honour. The Hebrew Bible (2 Kings 9:13) reports that Jehu, son of Jehoshaphat, was treated this way. Both the Synoptic Gospels and the Gospel of John report that people gave Jesus this form of honour. However, in the synoptics they are only reported as laying their garments and cut rushes on the street, whereas John specifies fronds of palm (Greek phoinix). In Jewish tradition, the palm is one of the Four Species carried for Sukkot, as prescribed for rejoicing at Leviticus 23:40.
The palm branch was a symbol of triumph and victory in the Greco-Roman culture of the Roman Empire, and became the most common attribute of the goddess Nike or Victory. For contemporary Roman observers, the procession would have evoked the Roman triumph,when the triumphator laid down his arms and wore the toga, the civilian garment of peace that might be ornamented with emblems of the palm. Although the Epistles of Paul refer to Jesus as "triumphing", the entry into Jerusalem may not have been regularly pictured as a triumphal procession in this sense before the 13th century. In ancient Egyptian religion, the palm was carried in funeral processions and represented eternal life. The palm branch later became a symbol of Christian martyrs and their spiritual victory or triumph over death.
