The history of Poles in the United States dates to the American Colonial era. Poles have lived in present-day United States territories for over 400 years—since 1608. There are 10 million Americans of Polish descent in the U.S. today. Polish Americans have always been the largest group of Slavic origin in the United States.

Historians divide Polish American immigration into three big waves, the largest lasting from 1870 to 1914, a second after World War II, and a third after Poland's regime change in 1989. Before those major waves, there was a small but steady trickle of migrants from Poland to the Thirteen Colonies and early United States, mainly comprising religious dissenters, skilled tradesmen, and adventurous nobles. Most Polish Americans are descended from the first major wave immigrants, which consisted of millions of Poles who departed parts of Poland annexed by Germany, Russia, and Austria. This migration is often called in Polish (for the bread), because most of the migrants were impoverished peasants, who owned little or no land, and often lacked basic subsistence. Large part of those lower class migrants came from the Austro-Hungarian province of Galicia, arguably the most destitute region in Europe at the time. Up to a third of Poles living in the United States returned to Poland after a few years, but the majority stayed. Substantial research and sociological works such as The Polish Peasant in Europe and America found that many Polish immigrants shared a common objective of acquiring farming land in the U.S. or making enough money to do the same back in Poland. Anti-migrant legislation substantially lowered Polish immigration in the period from 1921 to 1945, but it rose again after World War II to include many displaced persons from the Holocaust. 1945–1989, coinciding with the Communist rule in Poland, is the period of the second wave of Polish immigration to the U.S. A third, much smaller wave, came in 1989 after Poland transitioned to a multiparty market democracy.

Immigrants in all three waves were attracted by the high wages and ample job opportunities for unskilled manual labor in the United States, and were driven to jobs in American mining, meatpacking, construction, steelwork, and heavy industry—in many cases dominating these fields until the mid-20th century. Over 90% of Poles arrived and settled in communities with other Polish immigrants. These communities are called Polonia and the largest such community historically was in Chicago, Illinois. A key feature of Polish life in the Old World had been religion, and in the United States, Catholicism often became an integral part of Polish identity. In the United States, Polish immigrants created communities centered on Catholic religious services, and built hundreds of churches and parish schools in the 20th century.

The Polish today are well assimilated into American society. Average incomes have increased from well below average to above average today, and Poles continue to expand into white-collar professional and managerial roles. Poles are still well represented in blue collar construction and industrial trades, and many live in or near urban cities. They are well dispersed throughout the United States, intermarry at high levels, and have a very low rate of fluency in their ethnic language (less than 5% can speak Polish).

17th century

Virginia Colony

The first Polish immigrants came to the Jamestown colony in 1608, twelve years before the Pilgrims arrived in Massachusetts. These early settlers were brought as skilled artisans by the English soldier–adventurer Captain John Smith, and included a glass blower, a pitch and tar maker, a soap maker and a timberman. Historian John Radzilowski stated that these Poles were experts in pitch and tar making at the time and recruited to develop a key naval stores industry. He estimated that "two dozen Poles" at most were in the colony by 1620. In 1947, a purported historical diary, (A Memoir of a Merchant) was rumored to have surfaced in the United States which was to have been written by one of the original Polish settlers. Nonetheless, the Polish colonists led a strike in 1619 to protest their disenfranchisement in the New World; they had been excluded from voting rights by the first-ever legislative body. Their strike was the first labor protest in the New World.

The date of their arrival, October 1, 1608, is a commemorative holiday for Polish-Americans. Polish American Heritage Month is based on this month, and October 1 is commemorated annually in Polonia organizations. 2008 was considered the 400-year anniversary of Polish settlement in the United States, and 2019 is looked upon as the 400th celebration of the Jamestown strike, considered a fight for civil liberties, more specifically, their voting rights, and equal recognition regardless of ethnicity.

Religious exodus of Polish Protestants Protestant Poles left Poland for America seeking greater religious freedom. This was not due to the Counter-Reformation in Poland; in Poland, the Jesuits spread Catholicism chiefly by promoting religious education among the youth. After the Swedish Deluge, Polish Brethren, who were seen as Swedish sympathizers, were told to convert or leave the country. The Polish Brethren were banished by law from Poland in 1658, and faced physical fights, seizure of property, and court fines for preaching their religion. Polish exiles originally sought refuge in England, but lacking support, sought peace in America. The majority of exiled Poles arrived in New Sweden, although some had gone to New Amsterdam and the English Virginia colony. There is no evidence of Polish immigration to Catholic Spanish or French territories in North America in the 17th century, which historian Frank Mocha suggests is a signal that early Poles were Protestants and wanted to live with Protestants in America. These Poles were generally well educated and aristocratic. One known immigrant, pioneer Anthony Sadowski, had come from an area populated by Moravian Brethren and Arians in the Sandomierz Voivodeship of the Polish–Lithuanian Commonwealth, consistent with a religious exodus. Research has confirmed that one of his first actions upon arrival was visiting a Polish Protestant colony in New Jersey. He and his uncle, Stanisław Sadowski, converted to Calvinism before fleeing Poland. Abrycht Zaborowski (Zabriskie), a Polish Lutheran nobleman, arrived in the colonies in 1662. His grandson, Peter Zabriskie, was a friend and officer of George Washington.( Ref. The Revolutionary War in the Hackensack Valley. Leiby, Adrian C. Published by Rutgers University Press, 1962) Protestants (and other non-Catholics) regained their rights and religious freedoms in Poland in 1768, ending pressure to leave Poland on religious grounds.

18th century

American Revolution

Later Polish immigrants included Jakub Sadowski, who in 1770, settled in New York with his sonsthe first Europeans to penetrate as far as Kentucky. It is said that Sandusky, Ohio, was named after him, although the name is more likely derived from the Wyandot language in which "sa-un-dus-tee" means "water within pools" or "cold water". At the time, Polish–Lithuanian Commonwealth was failing and being gradually stripped of its independence due to military partitions by foreign powers, a number of Polish patriots, among them Casimir Pulaski and Tadeusz Kościuszko, left for America to fight in the American Revolutionary War.

Pulaski, having led the losing side of a civil war, escaped a death sentence by leaving for America. There, he served as Brigadier-general in the Continental Army and commanded its cavalry. He saved General George Washington's army at the Battle of Brandywine and died leading a cavalry charge at the Siege of Savannah, aged 31. Pułaski later become known as the "father of American cavalry". He is also commemorated in Casimir Pulaski Day and the Pulaski Day Parade.

Kościuszko was a professional military officer who served in the Continental Army in 1776 and was instrumental in the victories at the Battle of Saratoga and West Point. After returning to Poland, he led the failed Polish insurrection against Russia which ended with the Partition of Poland in 1795. Pułaski and Kościuszko both have statues in Washington, D.C.

One of other notable Polish Americans of the Revolutionary Era was Peter Zabriskie, a patriot and colonel in the Revolutionary Army, who opened his home in Hackensack to General Washington during the retreat from New York. General Washington came there after attempting to survey Mount Washington and learning of the attack on the troops stationed there. Writing to Congress from Hackensack concerning the surrender of troops at Mount Washington and the loss of material and cannon. Also to advise Congress of the British advance of troops in New Jersey to attack the Army, and General Washington's lack of forces to oppose them. His plan to Congress was retreat of forces and material across the Passaic River. Which was accomplished and further to Newark, New Brunswick, and Trenton. Peter Zabriskie became a judge in Bergen County and one of three Ratifying Signers to the Constitution for Bergen County, New Jersey.

After the Revolution, Americans who commented generally held positive views of the Polish people. Polish music such as mazurkas and krakowiaks were popular in the U.S. during the antebellum period. However, after the Civil War (1861–65) the image turned negative and Poles were stereotyped as crude and uneducated people who were not good fits for America socially or culturally.

19th century

Early settlements Panna Maria, Texas The first immigrants from Poland were Silesians from the Prussian partition of Poland. They settled in Texas in 1854, creating an agricultural community that carried their native traditions, customs, and language. The land they chose was bare, unpopulated countryside, and they erected the homes, churches, and municipal accommodations as a private community. The first home built by a Pole is the John Gawlik House, constructed 1858. The building still stands, and displays a high-pitched roof common in Eastern European architecture. The Poles in Texas built brick houses with thatched roofs until the 1900s. That region in Texas is subject to less than 1 inch of snow per year, and meteorological studies show that level of insulation is unwarranted. The Polish Texans modified their homes from their European models, building shaded verandas to escape the subtropical temperatures. They often added porches to their verandas, particularly on the southward windy side. According to oral histories recorded from descendants, the verandas were used for "almost all daily activities from preparing meals to dressing animal hides." Panna Maria, Texas, was often called a Polish colony because of its ethnic and cultural isolation from Texas, and remains an unincorporated community in Texas. The geographically isolated area continues to maintain its heritage but the population mostly moved to nearby Karnes City and Falls City.
