John Marshall Harlan was a very important American lawyer and judge. 

Harlan believed in the power of the national government. He thought the federal government should protect people's rights across every state. He also felt sympathy for people who did not have much money. He believed the Reconstruction Amendments changed how the government worked. These amendments were laws passed after the Civil War. These laws helped change the relationship between states and the national government. He was the first justice to argue for the Bill of Rights to apply to the states.
His life began in Kentucky in 1833. 
When the Civil War started in 1861, Harlan joined the Union Army. He was a Colonel in the 10th Kentucky Infantry. He worked hard to keep Kentucky part of the Union. He led his soldiers to defend important railroad bridges. One famous moment was at the Rolling Fork River Bridge. He helped protect supply lines from being destroyed. He served in the army until 1863. He left the military to care for his family after his father died.
Harlan's ideas were very ahead of his time. In 1883 and 1896, he was the only judge to disagree with decisions that allowed segregation. Segregation is when people are kept apart because of their race. He argued that the law should treat everyone equally. Many of his ideas did not become official law until the 1950s. His grandson, also named John Marshall Harlan II, later served on the Supreme Court too. Today, many scholars think he was one of the greatest judges ever. 
John Marshall Harlan was a significant American lawyer and politician. 

Harlan's legal philosophy focused on several core principles. He believed in the strength of the national government. He also felt great sympathy for the economically disadvantaged. Harlan argued that the Reconstruction Amendments had changed the American system. These amendments fundamentally altered the relationship between federal and state governments. He was the first justice to advocate for the incorporation of the Bill of Rights. This means applying the national Bill of Rights to the individual states. He also wrote a majority opinion regarding the Takings Clause in 1897.
As a justice, Harlan stood alone on several landmark cases. In the Civil Rights Cases of 1883, he was the sole dissenter. He also provided the only dissent in the famous Plessy v. Ferguson case in 1896. These cases involved decisions that allowed ethnic segregation in society. Harlan argued against these practices, believing in equal rights under the law. He also disagreed with decisions in Pollock v. Farmers' Loan & Trust Co. in 1895. That case struck down a federal income tax. He also dissented in cases involving antitrust actions and labor laws. His opinions included Lochner v. New York in 1905 and Standard Oil Co. of New Jersey v. United States in 1911. 
Harlan was born in 1833 near Danville, Kentucky. 
During the American Civil War, Harlan was a staunch Unionist. He worked to keep Kentucky from seceding from the Union. In 1861, he recruited and led the Crittenden Union Zouaves. He was later commissioned as a Colonel of the 10th Kentucky Volunteer Infantry. 
Harlan's political career continued after his military service. He was elected attorney general of Kentucky in 1863. He ran on a platform of vigorous prosecution of the war. Despite his Unionist views, his stances on slavery were complex. He originally opposed the Emancipation Proclamation. He also opposed the ratification of the Thirteenth Amendment. He did not emancipate his own household slaves until the amendment forced the change in 1865. Later, he became a leader of the Kentucky Republican Party. In 1877, President Rutherford B. Hayes appointed him to the Supreme Court.
The impact of Harlan's work grew long after his death. Many of his dissenting views became the official law of the land. This shift began with the Warren Court in the 1950s. Scholars now view him as one of the greatest justices of his time. His legal legacy even continued through his family. His grandson, John Marshall Harlan II, also served on the Supreme Court. He served from 1955 to 1971.
