The main issues that affected life & politics in England in the earlier 1800's where:
1) The Regency of Prince George of Wales (later George IV), whilst was offical from 1811, he had been effective regent since around 1800. This ear is called Regency, and gives names to furniture. He eventually became King in 1820 to 1830.
2) The Napoleonic Wars were happening all over Europe - England was involved in these but more as a Naval power, and with the use of financial subsidies to others European states, such as Prussia, to help them fight with armies against France. The British oin the gropund only got involved in Spain c1809, and then later on at Waterloo. So this cost a lot of money.
3) Part of Napoleons strategy to help defeat his enemies was a continential trade blockade that did not allow any non-French trade in or out of mainland Europe. This & the war in general had the affect of Britain falling behind the rst of europe in fashions, latest inovations, etc. So when people would come to visit they would note of the seemingly backwardsness of England.
4) There was the US-Anglo war that ended in 1812 - between the British their old american colonies. In the end the British had to sign of peace treaty with USA in order to end the war as it was too costly, especially with the Napoleonic Wars.
These are the main things (up to 1815) that dominated English life
