Sweden was called the “mother of peoples” by early historians and was the home of many of the barbarian tribes that overran the Roman Empire. It is the fifth largest country in Europe by area. An independent Swedish state emerged during the 12th century. In 1397, Sweden joined the Kalmar Union with Norway and Denmark, which joined the three kingdoms under a single monarch. Sweden left the union in 1523. Sweden ‘s involvement in the Thirty Years’ War (1618-1648) led to the expansion of its territories and the formation of the Swedish Empire. Between 1750 and 1850 the population doubled, and mass emigration was the result to avoid famine and rebellion. Beginning in 1820, approximately 1.3 million Swedes, a third of the country’s population, emigrated to North America, and most of them to the United States. There are more than 4.4 million Swedish Americans according to a 2006 U.S. Census Bureau estimate.
