Diamond Jubilee

This weekend was a four days weekend; named Jubilee weekend.

I sometimes heard the word "Jubilee" and it was also used for the name of a tube line, "Jubilee line", but I did not know the meaning.

We can find many Union Jack flags all around the cities and TVs have been continuously broadcasting special programs for the celebrations.

I realised that the British Empire was a large area and included many counties.

Although it is curious for us Japanese that European people (or at least for the British) can't tell Africa and Asia apart, I may have found the reason for it.

They had colonies all over the world, outside of Europe.

Their world may be composed of two parts; European countries and those outside of them.

If their cultures were based on such a history, it may be understandable.

The Jubilee gave me good chance to understand their culture and histories history.
