The Frontier of Islam: An Archaeobotanical Study of Agriculture in the Iberian Peninsula (c.700 – 1500 CE)

This PhD uses new archaeobotanical research and crop stable carbon (δ13C) isotope analysis to investigate medieval agriculture in the Iberian Peninsula (6th-15th centuries). It takes as its central theme an analysis of the long-standing debates surrounding the impact of the Islamic conquests (c.8th century) on agriculture. Were there major innovations after the conquests, or alternatively, was agriculture characterised by longer-term continuity? There is a long tradition of researching this topic in the Iberian Peninsula using documentary and archaeological evidence, yet archaeobotany has had little impact to date. Archaeobotanical research was undertaken on eight medieval sites in two study areas in the north-east of the peninsula. The first study area examined two Islamic sites (10th-12th centuries) in Teruel, whilst the second examined six sites dating between the early medieval, Islamic and later medieval periods (6th-15th centuries) in the Huecha Valley, Zaragoza. The archaeobotanical results point towards an overall pattern of continuity in the range of crops cultivated, although a general trend towards increasing crop diversity can be identified through time, reflecting broader patterns seen across medieval Europe and the Mediterranean. Stable carbon isotope analysis of 290 single-entity samples (cereals, pulses) provided insights into crop husbandry practices, highlighting the use of rainfed and irrigated areas for cultivation. The results of this PhD are placed within a wider regional and pan-regional context through a synthesis of previous archaeobotanical research undertaken on Roman to later medieval sites in the Iberian Peninsula. Taken together, it is suggested that the Islamic conquests did not lead to a clear and definable break in agriculture, but rather a series of more incremental and gradual changes can be identified through time. The results have wider implications for understanding the longer-term continuity of Mediterranean agriculture

English economic growth, 1270-1700

We provide annual estimates of GDP for England over the period 1270-1700, constructed from the output side. The GDP data are combined with population estimates to calculate GDP per capita. Sectoral price data and estimates of nominal GDP are also provided. We find per capita income growth of 0.20 per cent per annum, although growth was episodic, with the strongest growth after the Black Death and in the second half of the seventeenth century. Living standards in the late medieval period were well above “bare bones subsistence”, although levels of kilocalorie consumption per head were modest because of the very large share of pastoral production in agriculture

British economic growth : 1270 - 1870

We provide annual estimates of GDP for England between 1270 and 1700 and for Great Britain between 1700 and 1870, constructed from the output side. The GDP data are combined with population estimates to calculate GDP per capita. We find English per capita income growth of 0.20 per cent per annum between 1270 and 1700, although growth was episodic, with the strongest growth during the Black Death crisis of the fourteenth century and in the second half of the seventeenth century. For the period 1700-1870, we find British per capita income growth of 0.48 per cent, broadly in line with the widely accepted Crafts/Harley estimates. This modest trend growth in per capita income since 1270 suggests that, working back from the present, living standards in the late medieval period were well above “bare bones subsistence”. This can be reconciled with modest levels of kilocalorie consumption per head because of the very large share of pastoral production in agriculture

Space Climate Manifestation in Earth Prices - from Medieval England Up to Modern Usa

In this study we continue to search for possible manifestations of space weather influence on prices of agricultural products and consumables. We note that the connection between solar activity and prices is based on the causal chain that includes several nonlinear transition elements. These non-linear elements are characterized by threshold sensitivity to external parameters and lead to very inhomogeneous local sensitivity of the price to space weather conditions. It is noted that "soft type" models are the most adequate for description of this class of connections. Two main observational effects suitable for testing causal connections of this type of sensitivity are considered: burst-like price reactions on changes in solar activity and price asymmetry for selected phases of the sunspot cycle. The connection, discovered earlier for wheat prices of Medieval England, is examined in this work on the basis of another 700-year data set of consumable prices in England. Using the same technique as in the previous part of our work (Pistilnik and Yom Din 2004) we show that statistical parameters of the interval distributions for price bursts of consumables basket and for sunspot minimum states are similar one to another, like it was reported earlier for wheat price bursts. Possible sources of these consistencies between three different multiyear samples are discussed. For search of possible manifestations of the "space weather - wheat market" connection in modern time, we analyze dynamics of wheat prices in the USA in the twentieth century. We show that the wheat prices revealed a maximum/minimum price asymmetry consistent with the phases of the sunspot cycle. We discuss possible explanations of this observed asymmetry, unexpected under conditions of globalization of the modern wheat market.Comment: First International Symposium on Space Climate: Direct and Indirect Observations of Long-Term Solar Activity, 20-23 June 2004, Oulu, Finlan

Custom in context : Medieval and Early Modern Scotland and England

Studying custom and its context gives unique insights into relations of property, production and law in a society. The first part of the article discusses meaning in Scotland, focusing on ‘custom as normative practice, custom as unwritten law, and custom in opposition to law’. The second seeks to demonstrate (using evidence focusing principally on landholding) that custom as legal currency was more restricted for Scots than English. The third sets out the implications for continuity of landholding and for agrarian change in the Highlands of Scotland, an area where custom might be thought strong. The fourth deals with the differential legal development of Scotland and England between the twelfth and eighteenth centuries and its effects on social and tenurial relationships. A final section suggests why custom mattered more as a resource to the English, the domains in which it was important to Scots and the implications for understanding the comparative development of the two societies since the Middle Ages.PostprintPeer reviewe

Landholding and landscape in Ottoman Cyprus

In Ottoman Cyprus (1571–1878), social organization was based above all on the ownership and exploitation of agricultural land. The social relations, economic processes and daily practices of landowning elites and peasant farmers alike were structured by their relationship with the land. In this article, historical and archaeological data are integrated in order to investigate the development of social organization by focusing on landholding and landscape. In particular, it examines the role, identity and material culture of the new Cypriot/Ottoman elite, the commercialization of agriculture as expressed in the economy and the landscape, and the daily routine experiences of communities in the landscape

Accounting for the great divergence

This paper “accounts” for the Great Divergence between Europe and Asia in two ways. In the sense of measurement: (1) the traditional view, in which the Great Divergence had late medieval origins and was already well under way during the early modern period, is confirmed (2) However, revisionists are correct to point to regional variation within both continents (3) There was a Little Divergence within Europe, with a reversal of fortunes between the North Sea Area and Mediterranean Europe. (4) There was a Little Divergence within Asia, with Japan overtaking China and India. However, Japan started at a lower level of per capita income than the North Sea Area and grew at a slower rate, so continued to fall behind until after the Meiji Restoration of 1868. Any explanation needs to be able to account for the Little Divergences within Europe and Asia as well as the Great Divergence between the two continents. The divergences arose from the differential impact of shocks hitting economies with different structural features. The structural factors include: (1) The large share of pastoral farming in agriculture which helped to put the North Sea Area on the path to high-value-added, capital-intensive, non-human-energy intensive production. (2) Late marriage in the North Sea Area, which lowered fertility and encouraged human capital formation (3) Labour supply, with an industrious revolution helping to explain the Little Divergences within both Asia and Europe (4) Institutions, with the role of the state helping to explain the success of the North Sea Area. The two key shocks were (1) The Black Death, which led to a permanent per capita income gain in the North Sea Area, but not in the rest of Eurasia (2) The new trade routes which opened up from Europe to Asia and the Americas around 1500
