AbstractEnvironmental niche models predict the presence of the invasive Argentine ant in north-western Europe, especially along all the French Atlantic coast. Yet, the species has never been observed North from the 45th parallel in Europe, suggesting either that current models are wrong or that Argentine ants are already spreading north inconspicuously. Here, we report a three-hectare wide colony of Argentine ants, detected in 2016 in Nantes, France, which is 300 km north of the former northern-most outdoor population of this species in Europe. COI sequencing revealed that the haplotype of this new colony is the same as the one found in the so-called Catalonian supercolony, which is distinct from the haplotype found over most of the species range in Europe. Our discovery confirms models’ predictions that Argentine ants can colonize north-western Europe and suggests that they might have already reached several other locations along the French Atlantic coast. Detection surveys should be conducted in order to assess Argentine ants’ invasion patterns in Western France, particularly in high introduction risk areas such as major cities and maritime ports.

AbstractThe Holocene period (last 11,700 years BP) has been marked by significant climate variability over decadal to millennial timescales. The underlying mechanisms are still being debated, despite ocean–atmosphere–land connections put forward in many paleo-studies. Among the main drivers, involving a cluster of spectral signatures and shaping the climate of north-western Europe, are solar activity, the North Atlantic Oscillation (NAO) varying atmospheric regimes and North Atlantic oceanic gyre dynamics. Over the last 2500 years BP, paleo-environmental signals have been strongly affected by anthropogenic activities through deforestation and land use for crops, grazing, habitations, or access to resources. Palynological proxies (especially pollen grains and marine or freshwater microalgae) help to highlight such anthropogenic imprints over natural variability. Palynological analyses conducted in a macro-estuarine sedimentary environment of north-western France over the last 2500 years BP reveal a huge and atypical 300 year-long arboreal increase between 1700 and 1400 years BP (around 250 and 550 years AD) that we refer to as the ‘1.7–1.4 ka Arboreal Pollen rise event’ or ‘1.7–1.4 ka AP event’. Interestingly, the climatic 1700–1200 years BP interval coincides with evidence for the withdrawal of coastal societies in Brittany (NW France), in an unfavourable socio-economic context. We suggest that subpolar North Atlantic gyre strengthening and related increasing recurrence of storminess extremes may have affected long-term coastal anthropogenic trajectories resulting in a local collapse of coastal agrarian societies, partly forced by climatic degradation at the end of the Roman Period.

The precise dating and determination of the source of timbers in shipwrecks found around the coasts of the North Sea and the Baltic Sea, through dendrochronology allows us to see connections between north and  south, east and west throughout the region and to a high chronological precision. In this paper we take a look at results of recent analyses of timber from ships, and timber and barrel cargoes, to try to draw a chronological picture, from the twelfth to seventeenth centuries, of links between regions, through transport in oak ships and trade of timber. Archaeological finds of oak from timber cargos in shipwrecks and fine art objects (painted panels and sculpture) show the extent to which timber was shipped from Hanseatic towns along the southern Baltic coast, to western and north-western Europe.

This chapter explains the coverage of this book, which is about the comparison of rulers, warriors, traders, and clerics on the central Sahel and the North Sea region. It argues that there was more similarity between north-western Europe and the central Sahel in the few centuries either side of AD 1001 than has hitherto been recognised, and maintains that the nature of the sources has obscured these formative times and left them in the shadow of organised structures. It discusses the interconnectedness of central Sahel and north-west Europe through contacts and shared pre-industrial nature.

Abstract This paper charts communist print worlds in colonial India during the interwar period. Beginning in the early 1920s, self-declared ‘Communist’ and ‘Bolshevik’ publications began surfacing across India. Through the example of the Kirti Kisan Sabha (Workers and Peasants Party: a communist group in the north-western province of Punjab), and its associated publications, this paper will provide a glimpse into the rich, diverse and imaginative print worlds of Indian communism. From 1926 onwards, Kirti publications became a part of a thriving print culture in which a dizzying variety of revolutionary, socialist and communist publications competed and conversed with the equally prolific and rich print worlds of their political and ideological rivals. Removed on the one hand from the ivory towers of party intellectuals, dense treatises and officious theses, and on the other hand from the framing of sedition, rebellion and fanaticism in the colonial archive, Kirti publications show how the global project of communist internationalism became distinctly provincialized and vernacularized in British India.

For many years geologists have recognised the occurrence of at least two boulder-clays in the British Islands and the corresponding latitudes of the Continent. It is no longer doubted that these are the products of two separate and distinct glacial epochs. This has been demonstrated by the appearance of intercalated deposits of terrestrial, freshwater, or, as the case may be, marine origin. Such interglacial accumulations have been met with again and again in Britain, and they have likewise been detected at many places on the Continent, between the border of the North Sea and the heart of Russia. Their organic contents indicate in some cases cold climatic conditions; in others, they imply a climate not less temperate or even more genial than that which now obtains in the regions where they occur. Nor are such interglacial beds confined to northern and north-western Europe. In the Alpine Lands of the central and southern regions of our Continent they are equally well developed. Impressed by the growing strength of the evidence, it is no wonder that geologists, after a season of doubt, should at last agree in the conclusion that the glacial conditions of the Pleistocene period were interrupted by at least one protracted interglacial epoch. Not a few observers go further, and maintain that the evidence indicates more than this. They hold that three or even more glacial epochs supervened in Pleistocene times. This is the conclusion I reached many years ago, and I now purpose reviewing the evidence which has accumulated since then, in order to show how far it goes to support that conclusion.

During the excavations at Mycenae in 1953, a Protogeometric cist burial was discovered in the House of Shields, sunk into the floor of its west room. This burial, numbered Tomb PG 601, was published, with other burials, in BSA XLIX 258 ff. In the summer of 1954 Professor Wace uncovered three further burials in the House of Shields. These, at his most kind invitation, I publish here.General situation (Fig. 1). Whereas tomb PG 601 was found at the southern end of the west room of the House of Shields, these three, here numbered 602, 603, and 604, appeared in the north-western corner of this same room. Only a few feet separate the one from the others, as will be clear from the plan, and 602 and 603 seem to have been placed under the shelter of the west wall. The area had been to a certain extent disturbed, but whether there may have been further burials between 601 and this group of three I cannot tell. None was found in the excavation.

One of the key concepts of Max Weber's writings on cities was that in north-western Europe, the landed nobility and urban elites were clearly distinguished. For Weber, this was indeed a main reason to locate the occidental city in the north rather than in the Mediterranean. Christof Rolker tackles this question in his ‘Heraldische Orgien und Sozialer Aufstieg. Oder: Wo ist eigentlich “oben” in der spätmittelalterlichen Stadt?’, Zeitschrift für Historische Forschung, 52 (2015), 191–224. The in-depth analysis of one of the largest and at the same time most widespread armorials in the late medieval Holy Empire, namely that of Konrad Grünenberg (d. 1494), demonstrates that in Konstanz (where Grünenberg lived) guilds (and not the nobility) first insisted on patrilineal descent as a proof of status. Traditionally, Grünenberg is seen as a paradigmatic social climber, as he left his guild to join the society of the local nobility (called ‘Zur Katz’). Yet his sumptuous armorial, containing over 2,000 coat of arms mainly from the south-west of the Empire, does not mention any single member of this noble society. Instead, it praises the tournament societies of which Grünenberg was not a member, and highlights chivalric events in which he never participated. This, Rolker argues, indicates that armorials were not only about status already gained or to be gained, but also a manual for contemporaries to discuss the social order in a more abstract way. In his ‘Wappenbuch’, Grünenberg constantly explains why he could not join the noble societies he praised, while at the same time he ignored the ‘Zur Katz’ association of which he was a member. Therefore, Rolker concludes that it was not only members (or would-be members) of the respective social groups who knew and reproduced social codes. So the boundary between noble and urban elites was more blurred than Weber claimed – though Rolker is of course not the first to criticize Weber on this. Clearly, Grünenberg's armorial was part and parcel of a wider discussion of origins and kinship, namely patrilineal kinship that took place in several social milieux, rather than simply a book which displayed inherited status.

The number of publications on health technology assessment (HTA) from Central, Eastern, and Southern Europe (CESE countries) is still low compared with the north and west of Europe. It is not surprising, as the idea of HTA originated from high-income Western economies and was afterward adopted by the south-eastern part of Europe, which mostly consists of middle-income countries. These CESE countries, with less capacity and experience with HTA processes, must deal with even tougher decisions on financing health technologies than north-western Europe. There may even be a lack of confidence to open discussions on their specific needs for HTA.

AbstractThis article attempts to demonstrate that the notion of “Islamic world” was a creation of the modern age, emanating from north-western Europe in the nineteenth century. The term incorporates two opposing ideological meanings: on the one hand, Europe representing modern, positive values is set against the Islamic world, representing pre-modern, minus values, while on the other hand, the Islamic world was the common bond among all Muslims for their solidarity and unification against European colonialism. The article goes on to investigate why, how and when precisely the two concepts of “Islamic world” were created under the influence of modern European thought. It is stressed that in much of today's discourse too we can still perceive the two different meanings of the term, and this has often led to confusion and misunderstanding in discussion. Modern historians have played a role in substantiating the ideology of the “Islamic world”, because modern historiography has often described political objectives as actual reality.

This chapter discusses the Thirty Years' War. It shows that, when the Scots and then the English Protestants took up arms between 1638 and 1642 they followed the Dutch in committing to the defence of their Reformation by force. This was the first in a series of conflicts which did not secure Protestantism in England until 1689, or Calvinism in Scotland until 1707. These struggles on both sides of the North Sea were intertwined, beginning with a Scots rebellion supported by soldiers returning from the Netherlands and elsewhere, and ultimately hinging upon a Dutch invasion of England in 1688–9. In the long term, Reformation could only be defended in North-Western Europe by a multinational (and cross-confessional) military alliance against Louis XIV and James II.
