Thus, In the past, the flags have played an important role in society, which is also the case today. Every nation has a flag, whose colors are linked to the country's history, for example, orange in the Dutch flag represents the Orange Order which ruled the country before.
National flags are used to represent each country in conflict, sports competitions, international conferences and events, but they also give people a chance to show their patriotism by flying the flag of their nation.
This is particularly evident in England when a major football event happens; the majority of the population who are football fans fly the flag of St George to show they are behind English football team.
Clubs and organizations also have their own flags, such as the boy scouts, and all have a special meaning, but nevertheless are there for symbolic reasons.
Many organizations have taken on the importance of flags and manufacture them now for a wide range of customers. Piggotts is an example, and provides flags and flagpoles to places such as the Parliament buildings and other high-profile famous streets in London.
