Long ago, a group formed in the U.S. 

In the 1840s, a new group grew in the United States. 
Many new people were moving to the U.S. from Ireland and Germany. Many of these people were Catholic. The Know Nothings did not like them. They feared Catholic leaders would control voters. 
In 1854, the group became the American Party. They won many elections. They even elected Nathaniel P. Banks to Congress. In 1856, they ran Millard Fillmore for president. 
The Know Nothing movement was a major political group in the United States. It existed from the 1840s through the 1850s. People often called them the Know Nothings because of a secret rule. If an outsider asked about the group, members had to say, "I know nothing." 
The movement grew because many people were moving to the U.S. from Ireland and Germany. 
Secret groups helped the movement grow very quickly. One group was called the Order of the Star Spangled Banner. It was started by Charles B. Allen in New York City in 1849. At first, it only had 36 members. 
The group had many successes in elections during the 1850s. In 1854, they won many seats in Congress. They elected Nathaniel P. Banks to a seat in Congress. In the same year, they won many local offices in Massachusetts. In Chicago, Levi Boone was elected mayor in 1855. He even barred immigrants from getting city jobs. In 1856, the American Party ran Millard Fillmore for president. Fillmore was a former president. He received 21.5% of the popular vote in that election.
Even though they were powerful, the party did not last long. They had many weak leaders and no strong national leaders. They also split apart because of the big debate over slavery.
The Know Nothing movement was a powerful nativist political force in the United States. It operated primarily from the 1840s through the 1850s. Nativism refers to the desire to protect the interests of native-born citizens. This movement sought to defend traditional Protestant religious and political values. They often identified as the Native American Party or the American Party. The name "Know Nothing" came from their secret organizational style. 
This movement grew due to massive shifts in American population. Between 1840 and 1860, large numbers of Irish and German immigrants arrived. Many of these new arrivals were Roman Catholic. This created tension with the existing Protestant majority. 
Several secret societies acted as the mechanism for this movement. In 1849, Charles B. Allen founded the Order of the Star Spangled Banner in New York City. It began with only 36 members. 
Political success arrived rapidly during the mid-1850s. In 1854, the movement won many local and Congressional elections. They elected Nathaniel P. Banks to Congress in Massachusetts. In Chicago, Levi Boone was elected mayor in 1855 and barred immigrants from city jobs. In San Francisco, they helped elect J. Neely Johnson as governor. The party's membership exploded during this era. It grew from 50,000 members to over one million in just a few months. This massive surge allowed them to become a major alternative to the Democratic Party.
In the 1856 presidential election, the American Party nominated Millard Fillmore. Fillmore was a former president of the United States.
Despite their focus on nativism, the party held diverse political views. At the state level, some members supported progressive ideas. They advocated for labor rights and increased government spending. Some branches even supported the expansion of rights for women. They also supported regulating industry to help working people. This connection made them a forerunner of the later temperance movement. Interestingly, the movement did not focus its anger on Jewish people. In New York, the party even supported a Jewish candidate named Daniel Ullman for governor in 1854.
The movement eventually collapsed due to internal divisions and external pressures. They lacked experienced national leaders to hold the party together. A major cause of the split was the intense debate over slavery. The 1857 Dred Scott v. Sandford decision by the Supreme Court increased tensions. This decision pushed many former Know Nothings to join the Republican Party. In the South, the party struggled as leaders accused them of being abolitionists. By 1860, many remnants joined the Constitutional Union Party. The movement finally disappeared during the American Civil War.
