The First Thanksgiving: (The Pilgrims Missed It) On April 30th four centuries ago, our ancestors, led by Don Juan de Oñate, reached the banks of El Rio Bravo (Rio Grande). The first recorded act of thanksgiving by colonizing Europeans on this continent occurred on that April day in 1598 in Nuevo Mexico, about 25 miles south of what is now El Paso, Texas. After having begun their northward trek in March of that same year, the entire caravan was gathered at this point. The 400 person expedition included soldiers, families, servants, personal belongings, and livestock . . . virtually a living village. Two thirds of the colonizers were from the Iberian Peninsula (Spain, Portugal, and the Canary Islands). There was even one Greek and a man from Flanders! The rest were Mexican Indians and mestizos (mixed bloods).
