The Early 20th century was a time of optimism in Britain. The nation, with its expansive Empire, well-admired navy, thriving industry and strong political institutions, was what is now known as a global 'superpower'. It was also a time of social progress. Financial help for the unemployed, old-age pensions and free school meals were just a few of the important measures introduced. Various laws were passed to improve safety in the workplace; town planning rules were tightened to prevent the further development of slums; and better support was given to mothers and their children after divorce or separation. Local government became more democratic and a salary for members of Parliament (MPs) was introduced for the first time, making it easier for more people to take part in public life.
