What Is the History Behind the American Law?

The American legal system is rooted in a rich and complex history that spans centuries. From its origins in English common law to the present day, the American legal system has undergone significant changes and evolved into the complex and diverse system that it is today.

The Origins of American Law

The American legal system has its roots in English common law, which was developed over centuries of judicial decisions. Common law is a system of law based on custom and precedent rather than written statutes. It began to take shape in England during the Middle Ages, as local customs were codified and applied by judges in the courts.

The Influence of the Magna Carta

One of the most important documents in English legal history is the Magna Carta, which was signed by King John in 1215. The Magna Carta established important principles such as due process and trial by jury, which would later become key features of the American legal system.

The Development of Colonial Law

When Europeans began to settle in North America, they brought with them their own legal systems. In many cases, these systems were based on English common law. However, as settlers established their own colonies with distinct economies and social structures, new laws had to be developed to regulate these societies.

The Revolutionary Era

The Revolutionary era marked a turning point in American legal history. The colonists’ struggle for independence from Great Britain led to the formation of a new nation and a new legal system.

The Declaration of Independence

The Declaration of Independence, signed on July 4th, 1776, declared the United States’ independence from Great Britain. It also articulated important principles such as “life, liberty, and the pursuit of happiness,” which would later be enshrined in US law.

The Constitution

In 1787, the US Constitution was ratified, establishing the framework for the American legal system. The Constitution established a federal system of government with a separation of powers between the executive, legislative, and judicial branches. It also established important individual rights such as freedom of speech and religion.

The Modern Era

Since its inception, the American legal system has continued to evolve and adapt to changing social and political circumstances.

The Civil Rights Movement

The Civil Rights Movement of the 1950s and 1960s brought about significant changes to American law. The movement sought to end racial segregation and discrimination, leading to landmark Supreme Court decisions such as Brown v. Board of Education (1954), which declared segregation in public schools unconstitutional.

The Digital Age

The advent of the digital age has brought about new challenges for American law. Issues such as online privacy, intellectual property rights, and cybercrime have all required new laws and regulations to be developed.


The history of American law is a long and complex one that has been shaped by a wide range of social, political, and economic factors. From its origins in English common law to the present day, the American legal system has undergone significant changes but continues to be one of the most important pillars of US society.
