Oooo, not surprisingly, we find it in many traditions - as in dancing for the start of the summer, everything light and blossom and coming into bud, wherever you are:
"Maypole dancing is a widely distributed folk tradition with roots in ancient European spring rites, often viewed as a symbol of fertility, community, and the "Tree of Life". While strongly associated with England, it is a multicultural tradition, with variations found across Europe, North Africa, India, and the Americas"
There are some lovely U tube videos and I was delighted to find there is one in the park quite near me each year, I never knew.
