In 1620 the first pilgrims who traveled to the United States from England on the Mayflower boat were considered  the first north americans’ immigrants which were integrated to locals from that place who taught some important details. When autumn arrived the pilgrims cooked a big dinner to all natives in appreciation for that support provided and  for the good crop obtained that year.  Since then families and friends gather every fourth thursday of november  in order to thank each year.
