For the city of Liverpool, I only know football and the Beatles. But when I walked into the city, I found that the surprises that brought me did not stop there. Liverpool is like the episode of the rise and fall of Great Britain. Nowadays, nearly 3,000 buildings in the city were built in the 18th century, and the heavy sense of history can be felt everywhere in the streets. There are two arguments about Liverpool's name. One is that Liverpool was called "Liuerpul" in the 12th century, meaning a muddy pond or creek; the other is from "elverpool". Name, there used to be a lot of squid in the Mersey River (the eel of squid is English). It is generally believed that the city of Liverpool originated in August 1207, when King John made a command to establish Liverpool, but until the mid-16th century, Liverpool was only a small town with a population of only 500. It was not until the British Civil War in the 1650s that Liverpools trade and population began to grow slowly. In 1699, Liverpool became a parish. In the same year, the first slave ship of the Liverpool merchants sailed in Africa. Entering the eighteenth century, trade with the West Indies exceeded trade with Ireland and Europe, and Liverpool began to grow. In 1715 Liverpool built the first dock in the UK, and the profits of the slave trade helped the city to prosper quickly. By the end of the 18th century, Liverpool controlled 41% of Europe and 80% of the British slave trade. It is also one of the main areas of the British Industrial Revolution. By the early nineteenth century, 40% of the world trade had passed through the Liverpool dock. In 1830, the world's first passenger railway was opened between Liverpool and Manchester. Liverpool's population continues to grow rapidly and eventually becomes the second largest city in the UK.
