When and why did the Portuguese become the shortest Europeans? In order to find the answer to this question, we trace the trend in Portuguese living standards from the 1720s until recent times.We find that during the early nineteenth century average height in Portugal did not differ significantly from average height in most other European countries, but that when, around 1850, European anthropometric values began to climb sharply, Portugal's did not. In a panel analysis of 12 countries, we find that delay in human-capital formation was the chief factor hindering any improvement in the biological standard of living in Portugal.I t was Portugal's fifteenth-and sixteenth-century seafaring scientists and explorers who placed this small country at the cutting edge of maritime science and navigation and thereby transformed the global status of the rest of Europe as well. Their expeditions along the African west coast and to Latin America, not to mention Vasco da Gama's discovery, on his first voyage (1497-9), of the sea route to India, transformed their contemporaries' consciousness of the world that lay beyond the horizon. However, since those glory days the Portuguese have come to feel that their country lags behind the rest of Europe-and they are right, if anthropometry is taken as a welfare indicator: recent data indicate that the Portuguese are on average shorter than any other European nationality.2 When and why did the Portuguese slip to last place in the European height race?To tackle this question, a two-step approach is adopted. First, height development is reconstructed over almost three centuries, from the 1720s to the 1980s, and it is found that at the beginning of that time span Portuguese heights were in
