Food was rudimentary and based on Spanish tradition until immigration at end of the 19th century and the beginning of the 20th century, when the first families came mostly from Italy and Spain. Immigration increased following World War I and World War II, when people from all over Europe and the Middle East came to Uruguay, including people from Germany, Russia, Italy, and Armenia. Such immigration enriched the importation of dishes, as there is now pasta, Russian salad and innumerable types of pastries from France and Germany, resulting in chajá and alfajores.
