The events that occurred in Derry on 30th Jan 1972 became known as 'Bloody Sunday'. Why have these events produced such different historical interpretations?
And I have some sources to analyse but for the introduction I need to talk about Internment, and I can not find any web pages on it, if you know of any please could you reply

Thankyouu x

I suspect this will be more than you need on the introduction of internment itself.

What I suspect you need to know is the results of internment.
There is a little here.
Ans there is a little more towards the bottom of this page.

The main point for your essay, of course, is that the march on Bloody Sunday was a NICRA march against internment.

As part of your conclusion you might mention that the official British government report into the events of 1972, the Saville report, has still not been published. It is due before the end of this year and, for some, may give partial resolution of Ireland's bloody recent history.

See the Telegraph's report from 2008:

Bloody Sunday report delayed by another year, says Lord Saville - Telegraph
