From the sixteenth to mid seventeenth century, London benefited from the centralized politics and the maritime trade expansion developed by the Tudors and continued by the Stuarts. During Henry VIII's reign London had 100,000 inhabitants. In mid seventeenth century it had over 500,000.
In 1665, the city was still held inside the ancient walls although large urban planning had already started. The population's poor living conditions were responsible for the Great Plague, killing 70,000 people. The following year, a huge fire burnt down most of the city. The reconstruction of London, which in that time is where The City is now, took over 10 years to finish. The architect Christopher Wren's masterpieces such as St. Paul's Cathedral made London a lot more appealing. Thus, the capital became the center of English social life with palaces, halls, theatres, societies (Royal Society, 1662) and museums (British Museum, 1753).
London continued to grow thanks to the foundation of the Bank of England in 1694.
Most of current London is from the Victorian period. Up until the early years of the nineteenth century, the capital was confined to the boundaries of the original Roman city, as well as Westminster and Mayfair, and was surrounded by fields. Be that as it may, the Industrial Revolution drew millions of people to London, expanding the city. The overcrowded conditions led to grave problems like the 1832 cholera epidemics, or the great stink in 1858, an event that took place during the hottest months of the summer, exacerbating the smell of the sewers that were dumped in the River Thames, which led to the suspension of the parliamentary sessions.
From 1750, the population increased from 700,000 to over 4,500,000 in 1901 (6,600,000 if we include the suburban areas). At the end of the nineteenth century, London had become the international trade and finance capital.
The administrative needs of a city with so much commercial activity led the creation of a new autonomous territorial unit in 1888, the County of London, ruled by the "London county council". This county was divided into twenty-nine electoral units (the city and 28 metropolitan boroughs), but the progressive expansion soon overflowed outside the county boundaries to the suburban areas. After a steady period, the population of the capital began to decline at the end of World War I and fell below 3.5 million by 1950. In contrast, the suburban area grew steadily.
In 1963 a new division of the London agglomeration was made, comprising the old town and 32 metropolitan boroughs.
