Extract A After 1966, party distinctions in West Germany became blurred. The Grand Coalition of 1966–69 set Germany back on track in the most difficult of circumstances, effectively resolving the economic problems of the mid-1960s. This government greatly contributed to the political consensus of the following two decades. In 1974, nobody seemed better equipped to deal with a new economic crisis than Helmut Schmidt. Most Germans, including many traditional CDU/CSU voters, saw Schmidt as ...

Extract A The expansion of the British Empire was fuelled by the Victorians’ love of adventure and a desire for new knowledge. The interior of Africa held the most enticing mysteries left in the world. The public at home shared the thrill of discovery of the man on the spot. The Victorians loved a hero and imperial explorers and quarrelsome scientists filled this role. These men wrote long, and often dramatic, accounts of their experiences for their public and government at home to demon...

Extract A Industrialisation quickly broke up traditional social patterns which had existed for centuries. Living conditions in industrial towns, even more than working conditions, created new and terrifying problems. The new urban environment, affecting a steadily rising proportion of the nation, brought problems of poor living conditions and of social controls, just as much as factory employment brought the problems of discipline and regularity in work. Industrialists solved their problem...

Source A From an editorial in the Daily Mail, 3 November 1927. This newspaper, which was owned by the right-wing Lord Rothermere, ran a year-long campaign against widening the franchise. The great majority of Conservative voters are convinced that ‘votes for flappers’ will mean ‘votes for the Labour Party’. The last extension of the franchise has already created an enormous mass of voters who, no doubt, are well-meaning enough but do not have the political sense needed to make dem...

Extract A In the chaos of October 1905, Nicholas promised Russia a government that was constitutional in character. Although the right to vote was still restricted, there was an elected Duma and individuals could meet and organise themselves openly, as well as take an active role in political life. The first Duma held fairly moderate views and the second even more so. By 1907 order had been restored and between 1907 and 1914 Russia enjoyed a period of political calm during which wounds beg...

Extract A The living conditions and jobs of workers did not worsen from the 1780s to 1812. Even though industrial processes developed rapidly, there were still many economic activities that were not affected very much by new inventions by 1812. Also, cities were not terrible places for workers. The workers took pride in their cities and enjoyed freedom from control by landowners there. Average incomes rose for most workers from the 1780s. Although some workers did not benefit from changes,...

The Crusader States were the result of religious enthusiasm in the West. Many pilgrims rushed to Outremer as soon as the capture of Jerusalem in 1099 became known. Nowhere else were there so many sites so important to Christians, nor was there a better place to end one’s days. They did not come alone because the people who hoped to survive on the charity of pilgrims and the institutions created to help them also went. During the summer, the ports of Jaffa, Acre and Tyre, were heaving with...
