This has been one of the most important festivals of the Ahom since at least their arrival in Assam in the 12th century. 

It is a festival to show respect to the departed ancestors and remember their contribution to society. 

The word ‘Me’ means offerings. ‘Dam’ means ancestors and ‘Phi’ means gods. So while this festival is seen as ancestor worship, the name reflects the Ahom belief that ancestors soon turn to gods, when an individual’s immortal soul joins with the soul of the supreme being. 

During Me-dam-me-phi, three Gods: Grihadam, Dam Changphi, and Me Dam Me Phi, the god of heaven, are worshipped and offered gifts. 

For families, the ceremony remains intimate and usually takes place in the kitchen. A pillar called Damkhuta is created, which becomes the focus for worship and to place offerings such as homemade wine, mah-prasad (beans and chickpeas), and rice with meat and fish. 

A public ceremony for Me-dam-me-Phi has taken place in Charaideo, Assam for over 400 years. Charaideo was the first permanent capital of the Ahom kingdom from the 13th century and was the burial site for the kings of the Ahom dynasty.
