Kenya has rarely been considered a major Cold War battleground, becoming linked with Britain and the Western side, even whilst being publicly committed to non-alignment and African Socialism. Nonetheless, the Cold War offered opportunities for Kenya’s newly independent leaders. It was utilised in factional political debates between Tom Mboya and Oginga Odinga. In the late 1960s, leading Kenyans around President Jomo Kenyatta used Cold War rhetoric and rivalries to bargain to their advantage with the British over arms sales. British policy-makers offered concessions as they worked to build and then maintain their position as Kenya’s closest foreign partner.  相似文献

Chemical analysis of residue extracted from stone pipes and pipe fragments excavated at sites in the southern Pacific Northwest Coast of North America demonstrate that hunter-gatherers smoked the psychostimulant tobacco (Nicotiana sp.) by at least AD 860. Non-farming ethno-historic Native Americans throughout the west gathered and sometimes cultivated tobacco for ritual and religious purposes, but until now the antiquity of the practice on this part of the continent was unknown. Method validation includes chemical characterization of a suite of smoke plants and experimental reproduction of “smoked” pipe chemistry; results indicate biomarkers are traceable for several species commonly smoked by ethnographic native peoples, including tobacco (nicotine, cotinine), tree tobacco (anabasine), and kinnikinnick (arbutin). Developed methods—where residue is extracted directly from the stone or clay matrix of whole and fragmentary archaeological pipes—may be applied in similar studies investigating the spread and use of ritual smoke plants in the ancient Americas and elsewhere.  相似文献

Despite the enormous potential of anadromous fish, foragers do not mass extract and store salmonids until very late in the archaeological record of California. Acorns, by contrast, were intensively used quite early in the record. Salmon are traditionally viewed as a low cost, high ranking resource, and acorns as a high cost, low ranking resource. The question thus arises: why were salmon not used and stored en masse much earlier? We offer a solution using a simple foraging model that distinguishes resources on their storage as well as overall cost, making it possible to calculate the risk of resource caching, which appears to have delayed intensive salmon procurement in California.  相似文献

In April 1965, the rumour of a potential Kenyan coup was brought to British attention. This was a moment of raised tensions in the government of President Jomo Kenyatta, who secretly asked the British government for a military commitment to support his government if a coup was attempted by Kenyan Vice President Oginga Odinga. The British military responded by making an extensive military plan to intervene, code-named Operation Binnacle. They sent ships to Mombasa and put troops on alert. This article assesses these plans as a case study of the logic, and limits, of British military interventionism in the years after decolonization. It highlights the importance of studying plans, even when not carried out, and of taking seriously the attitudes and fears of contemporaries. Although a coup was highly unlikely, British reactions are revealing of their concerns about independent Kenya, including possible Soviet involvement. Operation Binnacle was a serious British response to the threat, as they saw it, which a coup would cause to their interests. These were extensive enough that the British government was prepared to intervene militarily, during a brief moment when military interventionism in Africa was still seriously considered as a possible policy choice.  相似文献
