From The American Presidency Project, Proclamation 5548—Polish American Heritage Month, 1986:
“In October, we celebrate Polish American Heritage Month in the United States. Our Nation owes an immeasurable debt of gratitude to the millions of freedom-loving Poles who have come to our shores to build a new land. Polish Americans can be justly proud of the vital contributions people of Polish descent have made to our Nation in the arts, the sciences, religion, scholarship, and every area of endeavor.
“The military genius of Kosciuszko and Pulaski was essential in the defense of our freedoms in the Revolutionary War. Since then, millions of Poland's sons and daughters have helped build our country's prosperity and defend our liberty.”
From the Central Intelligence Agency, The World Factbook, Poland:
“During the 18th century, internal disorders weakened the nation, and in a series of agreements between 1772 and 1795, Russia, Prussia, and Austria partitioned Poland among themselves. Poland regained its independence in 1918 only to be overrun by Germany and the Soviet Union in World War II. It became a Soviet satellite state following the war. Labor turmoil in 1980 led to the formation of the independent trade union "Solidarity" that over time became a political force with over 10 million members. Free elections in 1989 and 1990 won Solidarity control of the parliament and the presidency, bringing the communist era to a close. A "shock therapy" program during the early 1990s enabled the country to transform its economy into one of the most robust in Central Europe. Poland joined NATO in 1999 and the EU in 2004.”
