Customs of erecting decorated trees in winter time can be traced to Christmas celebrations in Renaissance-era guilds in Northern Germany and Livonia. The first evidence of decorated trees associated with Christmas Day are trees in guildhalls decorated with sweets to be enjoyed by the apprentices and children. In Livonia (present-day Estonia and Latvia), in 1441, 1442, 1510, and 1514, the Brotherhood of Blackheads erected a tree for the holidays in their guild houses in Reval (now Tallinn) and Riga. On the last night of the celebrations leading up to the holidays, the tree was taken to the Town Hall Square, where the members of the brotherhood danced around it.
