Presidential Proclamation 2016
From the Library of Congress: “At the turn of the 20th century, Polish immigration exploded. Imperial repression, land shortages and chronic unemployment made life more and more untenable for the Poles of Europe, and as the 19th century waned they left for America by the thousands, then by the hundreds of thousands. Exact numbers are difficult to come by, given the many different routes Poles took to the U.S., but the 1910 census found more than 900,000 new immigrants who spoke Polish. After World War I, Poland regained its independence, and immigration began to slow. Even so, it is estimated that more than 2 million Poles had immigrated by the 1920s.”
