One difference is the Klan had a lot more power. They were able to lynch innocent black people or persecute Jews and Catholics, and suffer no punishment, since all-white and all Protestant juries would generally refuse to convict. Another difference is the Klan dominated local government in many southern cities. Even some judges were members. This meant that it was nearly impossible for minorities to get justice.
The Klan's membership increased dramatically in the 1920s, and there was a reason for that. It was an era of great social change, when women got the right to vote, millions of immigrants were settling here, there were new inventions (like radio), and a growing number of black people were moving north to seek a better life away from segregation. Even some southern blacks were attending colleges and trying to move up in society.
Whenever there is social change, there is also a backlash. The rise of the Klan in the 1920s was undoubtedly a reaction to the many social changes that made most southern whites (and even some northern whites) very uncomfortable. Today, segregation is no longer allowed (as it was in the 1920s), and it is doubtful judges would brag about belonging to a racist organization. In the 1920s, the Klan was powerful; today, most people do not take it very seriously. Today, most white people know and work with black people, and few if any white people want to see a return to lynching, segregation, or the glorification of racism. In the 1920s, many thought the KKK were heroic; few people feel that way today, even in the south.
The KKK
The KKK of the 1920s was strongest in Indiana.
The "KKK of the 1920s," established in 1915, called itself the Ku Klux Klan or KKK.
KKK
The KKK actively recruited members in the 1920s. Later, Sen. Harry Byrd would become a KKK recruiter.
The KKK is a secret organization. However, there were KKK groups in Pennsylvania is the 1920, largely because of its staunch support of National Prohibition.
The KKK re-emerged in the 1920s largely but not entirely, to promote and illegally enforce National Prohibition.
A movie called Birth of a Nation was part of what causes the reemergence of the KKK in the 1920s. Another reason for the reemergence was the changes in the country, some did not like these changes.
The KKK of the 1920s differed significantly from the Reconstruction Era KKK in its broader focus and membership. While the original KKK primarily targeted Black Americans and sought to maintain white supremacy in the South, the 1920s KKK expanded its agenda to include a wide range of anti-immigrant, anti-Catholic, and anti-Semitic sentiments, reflecting a reaction to the changing social dynamics of the time. This version of the KKK also saw a massive increase in membership and visibility, promoting itself as a national organization with a more mainstream appeal, utilizing parades and public rallies to recruit members. Additionally, the 1920s KKK leveraged modern media and a more organized structure to spread its message beyond the South.

A second KKK, called the Klan of the 1920s, was actually formed in 1915 at Stone Mountain, Georgia.
