You will find as annex documents the timeline / chronology of the major steps of the Troubles that took place in Northern Ireland between 1968 and 1998. 

The toolbox will help you understand a few words and notions related to the Troubles and the different actors that took part in / partook in it.

I don't ask you to know by heart / by rote all these events, yet some are crucial to understand the evolution of the Troubles, why the period turned out so violent and why the demonstrators / protesters became so agitated:
- the Civil Rights Movement in 1967
- the Activation of the Internment Law in 1971
- Bloody Sunday in 1972
- Direct Rule in 1972
- The Good Friday Agreement in 1998.

You must be able to define and explain what happened for these five events.

You will also find below BBC's 2002 documentary film entitled Bloody Sunday which I advise / recommend you to watch. It faithfully illustrates how the 1972 tragic event in Derry occurred and how the issue was dealt with from a political point of view.
