Marine insurance is one of the oldest forms of insurance in the world. Long before health or automobile insurance came into being, seafarers and merchants found ways to protect their cargo and ships from the unpredictable dangers of the ocean. The history of marine insurance is not only a tale of commerce and law—it’s a story that runs parallel to the growth of global trade and maritime exploration.

In this blog, we’ll walk through the history of marine insurance, its origins, development over the centuries, and how it shaped the modern insurance industry we know today.

The Origins: Ancient Beginnings

The history of marine insurance dates back to ancient civilizations. There is evidence suggesting that around 3000 BCE, Chinese merchants redistributed cargo across multiple vessels to reduce the risk of loss during river transport. This rudimentary risk-spreading method laid the foundation for future insurance practices.

In ancient Babylon (circa 1750 BCE), the Code of Hammurabi included clauses for loans on shipments. If the cargo was lost to piracy or storm, the borrower was not held liable—a principle that reflects early forms of marine risk-sharing.

By 400 BCE, Greek and Roman traders were practicing a form of maritime loan called "bottomry", where a loan was given for a voyage and only repaid if the ship arrived safely. Though not insurance in the modern sense, it mirrored the risk-transfer mechanisms used today.

Medieval Europe: Formalizing Risk

The history of marine insurance took a major leap forward during the Middle Ages. As maritime trade expanded across the Mediterranean and North Atlantic, the need for structured risk management grew.

By the 12th century, merchants in Genoa and Venice were using written insurance contracts. These early policies were simple agreements to indemnify losses due to shipwrecks, piracy, or storms, and they were legally recognized in local courts.

In 1347, the earliest known marine insurance contract was signed in Genoa, Italy, establishing key terms such as the premium, voyage details, and perils covered. This marked the start of marine insurance as a formal business activity.

Renaissance to Early Modern Period: London’s Role

The history of marine insurance continued evolving during the Renaissance as European powers expanded their overseas empires. England, Spain, Portugal, and the Netherlands all engaged in global trade, increasing the number of seafaring voyages—and associated risks.

In the 17th century, London emerged as a global insurance hub. Merchants and shipowners gathered at coffeehouses along the Thames to discuss shipping news and negotiate coverage. One such location, Lloyd’s Coffee House, became the foundation for what would later be known as the Lloyd’s market—one of the most prominent insurance exchanges in the world.

The Marine Insurance Act of 1745 in England helped regulate the industry and laid the groundwork for contract standards and legal enforcement.

Industrial Age and Global Expansion

The 18th and 19th centuries saw revolutionary changes in maritime trade. The invention of steamships, the opening of the Suez Canal, and increased global commerce all brought new opportunities and risks.

Insurers began to collect data, assess risks more scientifically, and refine policies to reflect emerging maritime challenges. This period also saw the rise of marine reinsurance, allowing insurers to spread large risks across multiple parties.

As empires expanded and global trade intensified, marine insurance followed. The modern international marine insurance market began to take shape, with established practices, legal frameworks, and professional underwriting.

20th and 21st Century: Digital and Global Integration

In the modern era, the history of marine insurance reflects the broader trends of technology, globalization, and data analytics. From handwritten contracts to digital policies, the industry has embraced innovation.

Today, marine insurance covers not just cargo and ships but also environmental liability, cyber threats to navigation systems, and terrorism-related losses. The use of satellite tracking, automated reporting, and big data has transformed underwriting practices.

According to global market data, marine insurance premiums reached over $30 billion globally in 2023. The industry remains vital, especially as maritime transport still handles about 80% of international trade.
