The First Thanksgiving was a Hispanic Tradition!
Celebrations and the giving of thanks to God for gifts received, have their roots in all religions and cultural traditions. Even in our largely secular society, acts of thanksgiving are enacted daily all over the world, in Christianity, Islam, Judaism, Buddhism and many other religions. Since the beginning of time, immemorial people have acknowledged their good fortune by special rituals, offerings or sacrifices. There has always been a tradition of celebrating Days of Fasting or Days of Thanksgiving.
In 1620 the Mayflower brought forth to this continent a group of settlers who carried on the traditions of their culture, religion and customs. Thanksgiving was part of their Christian and European lore and they simply continued doing what their ancestors had been celebrating for years.
