The British press – one of the noisiest, most opinionated and longest-running media institutions in the world – is known for its history of wide-ranging debate and reporting. Encompassing so many digital newspaper archives, the Gale Primary Sources programme offers a comprehensive view of the landscape of opinions and commentary which have featured in the British press at any one time. This makes it a great resource for those studying contemporary opinions about a particularly issue or controversy, or how attitudes have evolved over time. This is the first of two posts looking at how persuasion, debate and clashes of opinion have coloured the British press at particular historical moments; in this case, during the First World War. Next week I’ll be posting about the altercations that arose around the rise of Fascism. As well as some of the most well-known arguments, these posts will bring to the fore views which have now been side-lined, discredited or simply eclipsed by modern interpretations.
