Spanish conquistador Hernán Cortés arrived in Tenochtitlan on November 8, 1519. With an estimated population between 200,000 and 300,000, many scholars believe Tenochtitlan to have been among the largest cities in the world at that time.[14] Compared to Europe, only Paris, Venice and Constantinople might have rivaled it. It was five times the size of the London of Henry VIII.[6] In a letter to the Spanish king, Cortés wrote that Tenochtitlan was as large as Seville or Córdoba. Cortes' men were in awe at the sight of the splendid city and many wondered if they were dreaming.[15]
