In a world virtually free of slavery and colonialism and one mainly driven by the sovereign state rationale, allusion to manifestations or the existence of some form of these phenomena within a state is often received with dumbfounding indifference or denial. However, a form of rule that had continued in South Sudan long after the departure of the British in 1956 was colonial both in its quintessence and flair in that it disenfranchised its citizens and denied them the most basic freedoms, services and development. Under this establishment, resistance against the coercive vision of the state was brutally suppressed for many decades. This state of affairs finally ended in July 2011. Nonetheless, there is a miscellany of unresolved post-colonial issues between the two countries that warrant attention. These include security and the demarcation of borders, the issue of ludicrous transit fees for South Sudan's oil exportation through Sudan, citizenship, external debt repayment, etc. These issues are part of traps inherited from the anti-colonial struggle, which have now supplanted the old ensemble of North–South conflict paroxysm. As a matter of urgency, the two countries will have to wrap up the incomplete process of negotiation on these substantive issues. The talks should be approached with a new mindset based on the new reality of two sovereign states. To the extent that it is widely established that South Sudan and Sudan must coexist peacefully in order to develop into viable entities, such mutual dependency must be based on equality and respect. 相似文献

The paper re-interprets the implement known as the ‘Towton Battle Axe’ allegedly found in the river which borders the Towton Battlefield (1461), Yorkshire, England, and which now resides in Alnwick Castle, Northumberland. The paper provides parallels, in the form of comparisons with other weapons, in order that the Towton implement can be shown to be a modified former halberd dating from the early sixteenth century. It is, therefore, highly unlikely that the implement was used in the famous battle. 相似文献

AbstractAn argument is presented that Valentine Green’s mezzotint engraving ‘Queen Elizabeth at the Head of her Army at Tilbury-Fort, A.D. 1588’ (1792) was inspired by the late 18th-century life-sized group of three figures representing the same subject that was formerly on show at the Tower of London. The mezzotint presented in Acta Historica Reginarum Angliae is the only known image of the original pre-1828 setup of the display, showing the figure of the queen in a skirt-like piece of armour that has since been re-identified as King Henry VIII’s tonlet armour. 相似文献

AbstractThe princely garniture ‘commanded’ to be made by Prince Henry Frederick for his cousin, Prince Friedrich Ulrich, later Duke of Brunswick, from the Royal ‘Almain’ Armoury at Greenwich, during the stewardship of the Master Armourer, William Pickering, his son, John, and the men of the Greenwich workshop, is described, illustrated and discussed. Accounts are presented of the lives and work of the Pickerings and the evidence is reviewed for the manufacture of this last decorated garniture of the Greenwich School. 相似文献

This article argues that the prewar planning process for postwar Iraq was plagued by myriad problems, including a dysfunctional interagency process, overly optimistic assumptions, and a lack of contingency planning for alternative outcomes. These problems were compounded by a lack of civilian capacity during the occupation period, which led to a complicated and often uncoordinated relationship with the military authorities who found themselves taking the lead in many reconstruction activities. Taken together, these mistakes meant that US success on the battlefield was merely a prelude to a postwar insurgency whose outcome remains very much in doubt more than three years later. 相似文献

As the world becomes increasingly globalized, interruptions to international trade cannot be permitted. Piracy off the coast of Somalia has hampered international trade in the region and poses significant risks to the sailors required to navigate those waters. Over the past three years the global community has attempted, through a number of different naval tactics, to stop these acts of piracy; however, these tactics have proven ineffective. This article looks at historical precedence and military theory to support the concept of using convoys to protect the thousands of cargo vessels traveling round the Horn of Africa every year. This tactic will greatly decrease the number of successful pirate attacks and save countless lives in the process. 相似文献
