Riches to Ruins: The History of London from the Romans to the Great Fire

London, the capital of England and one of the world‘s most iconic cities, has a history that spans over two millennia. From its founding as a Roman settlement to its rise as a global center of commerce and culture, London has experienced countless triumphs and tragedies. In this article, we will explore the fascinating history of London from the Roman era to the devastating Great Fire of 1666, which forever changed the face of the city.

Londinium: The Roman Foundation (47 AD – 5th century)

The story of London begins in 47 AD, when the Romans established a settlement on the north bank of the River Thames, which they named Londinium. The town‘s strategic location made it an ideal hub for trade and commerce, and it quickly grew in importance within the Roman Empire.

Londinium was initially a small, fortified settlement, but it soon expanded to become a thriving city with a population of around 30,000 people at its peak. The Romans built impressive infrastructure, including a bridge across the Thames, a forum, an amphitheater, and a complex system of roads and sewers. The city also boasted a diverse population, with people from across the empire living and working within its walls.

Despite its prosperity, Londinium faced several challenges during the Roman period. In 60 AD, the city was burned to the ground by the Iceni tribe, led by Queen Boudica, during a rebellion against Roman rule. The city was rebuilt and fortified, but it later declined in the 4th and 5th centuries as the Roman Empire weakened and eventually withdrew from Britain.

Saxon and Viking London (5th century – 1066)

After the departure of the Romans, London was largely abandoned for several decades. It wasn‘t until the 6th and 7th centuries that the Saxons established a new settlement, known as Lundenwic, about a mile west of the old Roman city. This new London quickly grew in importance as a trading center, with merchants from across Europe visiting the city to buy and sell goods.

However, the Saxon city was not immune to the threats of the time. In the 9th century, London was repeatedly raided by Viking invaders, who plundered the city and caused great destruction. In response, King Alfred the Great of Wessex ordered the construction of a network of fortified towns, known as burhs, to defend against further attacks. London, renamed Lundenburg, was one of these burhs and became a key stronghold in Alfred‘s kingdom.

The Viking raids continued into the 11th century, with the Danish king Cnut the Great even ruling England from London for a time. However, the city‘s strategic importance ensured that it remained a vital center of trade and governance throughout the Saxon and Viking periods.

Medieval London (1066 – 1485)

The Norman Conquest of 1066 marked a turning point in London‘s history. William the Conqueror, recognizing the city‘s importance, granted London a charter that confirmed the rights and privileges of its citizens. Under Norman rule, London continued to grow and prosper, becoming one of the largest and most influential cities in Europe.

During the medieval period, London was a city of contrasts. On one hand, it was a center of wealth and power, with a thriving economy based on trade and commerce. The city was home to many guilds, which controlled the production and sale of goods, and the Livery Companies, which regulated various trades and crafts. London also became a hub of political power, with the Palace of Westminster serving as the seat of government and the Tower of London as a symbol of royal authority.

On the other hand, medieval London was also a city plagued by disease, poverty, and social unrest. The Black Death, which first struck the city in 1348, killed an estimated 40-60% of the population, and subsequent outbreaks occurred regularly throughout the 14th and 15th centuries. The city‘s crowded and unsanitary living conditions made it a breeding ground for disease, and the poor and marginalized often suffered the most.

Despite these challenges, London continued to grow and evolve during the medieval period. The city‘s population reached an estimated 80,000 by the end of the 15th century, making it one of the largest cities in Europe. The city also underwent significant physical changes, with the construction of new churches, guildhalls, and other public buildings that still stand today.

Tudor and Stuart London (1485 – 1666)

The Tudor and Stuart periods brought great change to London, both in terms of its physical appearance and its social and cultural life. Under the Tudors, London became a center of the English Renaissance, with a flourishing of art, literature, and theater. The city also underwent significant religious changes, with the English Reformation under Henry VIII leading to the dissolution of the monasteries and the establishment of the Church of England.

The Stuart period, which began in 1603 with the accession of James I, was a time of political upheaval and social unrest in London. The city was a stronghold of Parliamentarian support during the English Civil War (1642-1651), and it played a key role in the events that led to the execution of Charles I in 1649.

Despite the political turmoil, London continued to grow and prosper during the Stuart period. The city‘s population reached an estimated 500,000 by the mid-17th century, making it the largest city in Europe. The growth of international trade, particularly with the Americas and the East Indies, brought great wealth to the city, and London became a global center of commerce and finance.

However, the city‘s growth also brought new challenges, including overcrowding, poverty, and disease. The Great Plague of 1665-1666 killed an estimated 100,000 people in London, representing nearly a quarter of the city‘s population. The plague devastated communities and disrupted trade and commerce, leaving the city in a weakened state.

The Great Fire of London (1666)

The Great Fire of London, which began on September 2, 1666, was one of the most devastating events in the city‘s history. The fire started in a bakery on Pudding Lane and quickly spread through the city‘s narrow, winding streets and tightly packed wooden buildings. For four days, the fire raged out of control, destroying over 13,000 houses, 87 parish churches, and many of the city‘s most important public buildings, including St. Paul‘s Cathedral.

The response to the fire was slow and disorganized, with the city‘s firefighting equipment proving inadequate to the task. The Lord Mayor of London, Sir Thomas Bloodworth, famously dismissed the fire as a small matter and went back to bed, allowing the blaze to spread unchecked. It wasn‘t until the third day of the fire that more decisive action was taken, with the use of gunpowder to create firebreaks and the deployment of the Royal Navy to fight the flames from the River Thames.

The aftermath of the Great Fire was a time of great change and rebuilding for London. The city‘s streets were widened and straightened, and new building regulations were introduced to prevent the spread of future fires. The iconic St. Paul‘s Cathedral was rebuilt by Sir Christopher Wren, and a monument to the fire, known as The Monument, was erected near the site where the blaze began.

The Great Fire also had a profound impact on London‘s social and economic life. Many of the city‘s poorest residents, who had lost everything in the fire, were forced to leave London and seek new opportunities elsewhere. The rebuilding effort, which took decades to complete, created new jobs and economic opportunities, but it also exacerbated existing social and economic inequalities.


The history of London from the Roman era to the Great Fire of 1666 is a story of resilience, adaptation, and transformation. Through invasions, plagues, fires, and political upheavals, London has consistently risen from the ashes and reinvented itself as one of the world‘s great cities.

As a historian, I am struck by the ways in which London‘s past continues to shape its present and future. The city‘s Roman origins, medieval institutions, and early modern innovations all have echoes in the modern metropolis we know today. At the same time, the challenges and crises that London has faced throughout its history – from the Black Death to the Great Fire – remind us of the fragility of urban life and the need for constant adaptation and renewal.

In studying the history of London, we gain not only a deeper understanding of one of the world‘s most fascinating cities, but also insights into the broader forces that have shaped human societies over time. From the rise and fall of empires to the impact of disease and disaster, the story of London is, in many ways, the story of us all.
