Industrialisation created tension between the imperial powers. This tension was sparked by the need to gain power and control within Europe; only achieved through attaining a "place in the sun", or sharing the same success as the British empire.
Industrialisation brought social change. As a result, new idealogies were born to counter and challenge the existing order of society. These include: socialism, liberalism and anarchism. In particular, socialism and liberalism were largely embraced by the new emerging classes - the working and middle classes.
The 20th century saw an increase to urbanisation, where much of the population moved to the city, with the oppertunity to find work. Yet much of the workers were exploited, and accompanying urbanisation, came the idea of trade unionism.
The world was rapidly changing and these changes catalysed the growing conflict within Europe, soon to lead into World War I.
