Remembering war and loss, in part so it does not happen again
The Great War began in 1914, more than a century ago, and is not that far back in history.
There are still people alive who lived through the entirety of that disastrous conflict.
Indeed, Maud Nicholl, until recently the oldest person in Northern Ireland, indeed in Ireland, was born a full five years before that war began yet she died only a few weeks ago.

In other words, the world wars in many respects seem so far back as to be like they belong to a different planet, yet are very much a feature of our recent history.
While war survivors are themselves dwindling in number, tens of millions of their children are still alive and many hundreds of millions of their grandchildren.
This is why across Northern Ireland, and across the western world, Remembrance Sunday and Remembrance Day, which is today, is still so widely observed.
