Bhangra is a lively form of music and dance that originated in the Punjab region of India
Wikipedia says While Bhangra historians speculate the dance may have originated in the time of the wars with Alexander, no one is sure it existed until about five hundred years ago, when it was done by farmers on special and joyous occasions. Around the 14th or 15th Century, Punjabi wheat farmers danced and sang songs about village life to help pass the time while working in the fields. With time, these became part of harvest celebrations at Bhaisakhi (April 13) festivals, as the sight of their crops growing invigorated the farmers. From here the dance quickly moved through all divisions of class and education, eventually becoming a part of weddings, New Year parties, and other important occasions.
