London is the capital of the United Kingdom and England.  London is the city region with the highest population in the United Kingdom. With it being located along River Thames, London has been a central city since it was founded by the Romans two millennia ago under the name Londinium. London's original city center, the City of London, which in 2011 had 7,375 inhabitants on an area of 2.9 km², is England's smallest city. Since the end of the 19th century, London has also been used for the urban region that has developed around this city center.  This area forms the region of London, as well as the Greater London administrative unit,  led by the Mayor of London and the London Assembly. 
In modern times, London is one of the world's most important political, economic and cultural centers. This is not least due to the fact that London was the capital of the British Empire and thus for almost three centuries the center of power for large parts of the globe.
The city itself has around 9.1 million inhabitants (2018) , but if you count the entire metropolitan area of London (London Metropolitan Area), you reach around 15 million. The city is considered the largest in the EU by population. 
London has a temperate climate with regular, light rain throughout the year. July is the warmest month, with an average temperature at Greenwich of 13.6 ° C to 22.8 ° C. The coldest month is January, with an average of 2.4 ° C to 7.9 ° C. The average annual rainfall is 583.6 mm, and February is normally the driest month. Snow is uncommon in London itself, although there is regular snow in the surrounding area; this is because the extra heat the big city generates makes the city about 5 ° C warmer than surrounding areas in winter.
The Romans built the city of Londinium along the River Thames in the year AD 43 The name Londinium (and later 'London') came from the Celtic language of the Ancient Britons. In the year AD 61, the city was attacked and destroyed. Then the Romans rebuilt the city, and London became an important trading hub.
After the decline of the Roman Empire, few people remained in London. This was partly because the Anglo-Saxon people of Sub-Roman Britain were primarily agricultural. Once the Romans had gone, trade with Continental Europe dwindled. In the 9th century, more people started living in London again. It became the largest city in England. However, it did not become the capital city of England until the 12th century.
After the railways were built, London grew very big. Greater London has 33 London Boroughs (neighbourhoods) and a mayor. The old City of London is only a square mile in size but has its own Lord Mayor.
Another famous old part of Greater London is Westminster, which was always a different city from the City of London. In Westminster is Westminster Abbey (a cathedral), The Palace of Westminster (the Houses of Parliament, with Big Ben), and 10 Downing Street (where the Prime Minister lives).

London Transportation (Trains, airports and Metro)Edit
The city has a huge network of transport systems including trains, metros (underground) and five main airports.
The Victorians built many train systems in the mid-19th century (1850s). Their main stations are in London, and the lines go to every part of Great Britain. There were originally five major companies but the five companies became a national rail network in modern times.
There are five airports, though only one is actually in London (London City Airport). There is the London end of the London–Birmingham canal, which was important to the industrial 19th century. The most used airport is Heathrow International Airport although it is actually outside the city.
The metro or London Underground is a system of electric trains which are in London. It is the oldest underground railway in the world. It started running in 1863 as the Metropolitan Railway. After the opening the system was copied in many other cities, for example New York and Madrid. Even though it is called the Underground about half of it is above the ground. The "Tube" is a slang name for the London Underground, because the tunnels for some of the lines are round tubes running through the ground. The Underground has got 274 stations and over 408 km of track. From 2006–2007 over 1 billion passengers used the underground.
