The world we live in has changed greatly over the past 25 years. We have tried to capture just a few of the most dramatic developments in the areas of technology, science, transport and politics. Unfortunately tragic events such as natural disasters and conflict have also played their part over the last 25 years. We will be presenting some of these events here.

You will be able to test your knowledge while trying to remember the years in which certain events took place.

We will be providing links to other international organisations celebrating their 25th anniversary this year also, if you wish to find out more about them. From media organisations to other global aid and development agencies, they are all 25 years old.
