But the Yom Kippur War ended this era. Led by Saudi Arabia, the Arab states announced they would cut supplies of oil to Europe, Japan and the United States. Israel had to face the frightening possibility that it might not always be able to rely on the diplomatic support it had always found outside the region. It might not be able to go on counting on guilt about the Holocaust, sympathy and admiration for a progressive state in a backward region, and the influence of Jewish communities in the United States. It was not a good moment for the United States and its allies. In 1974, with 138 states members of the United Nations, there were for the first time majorities in the General Assembly against the western powers (over both Israel and South Africa). Though for the moment the United Nations agreed to put a force into Sinai to separate the Israelis and the Egyptians, none of the region’s fundamental problems was solved.
The impact of ‘oil diplomacy’ went far beyond the region, however. Overnight, economic problems that had been developing since the late 1960s became acute. World oil prices shot up. Dependence on oil imports everywhere played havoc with balance-of-payments problems. The United States, floundering in what had become an Indochinese morass, was badly shaken; Japan and Europe appeared to face full-scale recessions. Perhaps, it seemed, a new 1930s was on its way; at any rate, the golden age of assured economic growth seemed over. Meanwhile, it was the poorest countries among the oil importers that suffered most from the oil crisis. Many of them were soon having to face rocketing price inflation and some a virtual obliteration of the earnings they needed in order to pay interest on their large debts to foreign creditors.
The impact of higher oil prices was great in much of Africa. In the 1950s and early 1960s that continent had undergone a startlingly rapid process of decolonization. It had been exhilarating, but had left behind some fragile new states, especially south of the Sahara. France, Belgium and Great Britain were the major imperial powers concerned with what was on the whole a perhaps surprisingly peaceful process. Italy had lost her last African territories in 1943, and only in Algeria and the Portuguese colonies was there much blood spilled in the process of liberation, the Portuguese finally giving up after domestic revolution in 1974; thus the Iberians who had led the European adventure of overseas dominion were almost the last to abandon it. There was plenty of bloodshed to come after the roll-up of empire, it is true, when African set about African, but troubles tended to arise for the French and British only when there were significant white settler communities to consider. Elsewhere, both French and British politicians proved anxious to retain influence, if they could, by showing benevolent interest in their former subjects.
The outcome was an Africa that owes its present form in the main to decisions of nineteenth-century Europeans (just as much of the Middle East owes its political framework to the Europeans in the twentieth century). New African ‘nations’ were usually defined by the boundaries of former colonies and those boundaries have proved remarkably enduring. They often enclosed peoples of many languages, stocks and customs, over whom colonial administrations had provided little more than a formal unity. As Africa lacked the unifying influence of great indigenous civilizations, such as those of Asia, to offset the colonial fragmentation of the continent, imperial withdrawal was followed by its Balkanization. The doctrine of nationalism that appealed to the westernized African élites (Senegal, a Muslim country, had a president who wrote poetry in French and was an expert on Goethe) confirmed a continent’s fragmentation, often ignoring important realities that colonialism had contained or manipulated. The sometimes strident nationalist rhetoric of new rulers was often a response to the dangers of centrifugal forces. West Africans combed the historical record of ancient Mali and Ghana, and East Africans brooded over the past that might be hidden in relics, such as the ruins of Zimbabwe, in order to forge national mythologies like those of earlier nation-makers in Europe. Nationalism was as much the product of decolonization in black Africa as the cause.
