The palm branch, or palm frond, is a symbol of victory, triumph, peace, and eternal life originating in the ancient Near East and Mediterranean world. The palm (Phoenix) was sacred in Mesopotamian religions, and in ancient Egypt represented immortality. In Judaism, the lulav, a closed frond of the date palm is part of the of Sukkot. A palm branch was awarded to victorious athletes in ancient Greece, and a palm frond or the tree itself is one of the most common attributes of Victory personified in ancient Rome.
In Christianity, the palm branch is associated with Jesus' Triumphal Entry into Jerusalem, celebrated on Palm Sunday, when the Gospel of John says of the citizens, "they took palm branches and went out to meet Him" (12:13 HCSB). Additionally, the palm has meaning in Christian iconography, representing victory, i.e. the victory of the spirit over the flesh (Revelation 7:9).
Since a victory signals an end to a conflict or competition, the palm developed into a symbol of peace, a meaning it can have in Islam, where it is often associated with Paradise.
The palm appears on several flags or seals representing countries or other places, with the coconut palm associated with the tropics.
In Assyrian religion, the palm is one of the trees identified as the Sacred Tree connecting heaven, represented by the crown of the tree, and earth, the base of the trunk. Reliefs from the 9th century BC show winged genii holding palm fronds in the presence of the Sacred Tree. It is associated with the goddess Ishtar and is found on the Ishtar Gate. In ancient Mesopotamia, the date palm may have represented fertility in humans. The Mesopotamian goddess Inanna, who had a part in the sacred marriage ritual, was believed to make the dates abundant. Palm stems represented long life to the Ancient Egyptians, and the god Huh was often shown holding a palm stem in one or both hands. The palm was carried in Egyptian funeral processions to represent eternal life. The Kingdom of Nri (Igbo) used the omu, a tender palm frond, to sacralize and restrain.
