Ethnoregionalist movements across Western Europe are gaining scholarly attention. Central European states usually have limited places in those studies. Still, in Polish Upper Silesia, ethnoregionalist movements have been present since 1989 and have stable support from the inhabitants of the region. Since at least 2002, ethnoregionalists have attempted to secure political representation among the Upper Silesians. Recently registered parties have used the ethnic identity of this minority group as the main tool to gain support in political elections in the region. This article applies social science and political science perspectives to the politicization of ethnicity. These equip the researcher to answer the question: How has Silesian ethnic identity become politicized? In responding, the researcher explores the consequences of the emergence of the ethnoregionalist movement in Upper Silesia.

This study in comparative global history sheds light on a largely ignored forum for the politics of transition from monarchical empire to nation-state in the Middle East and Central Europe—religious festivals at sacred shrines. It compares the role of key pilgrimage festivals at politically important sacred shrines: (1) the Islamic Nabi Musa (Prophet Moses) pilgrimage to the Haram esh-Sharif and Nabi Musa Tomb near the Dead Sea in Mandatory Palestine and (2) various Catholic pilgrimages to Jasna Góra in Częstochowa in interwar Poland. The author demonstrates how these events served as sacred forums for secular politics, where various political factions contested their partisan ideas of the nation, which included the elite nationalism of Grand Mufti of Jerusalem Hajj Amin al-Husseini and the Catholic-Endecja nationalism of Polish clerical leaders. Moreover, I examine the role of these pilgrimage festivals in some of the major conflicts afflicting their respective areas, such as Arab–Jewish violence and hostility in Palestine and wars for borders as well as anti-minority sentiment, especially anti-Semitism, in Poland.

Ammonioalunite, ammoniojarosite and their solid-solution series found on a burning coal dump at Czerwionka, Upper Silesian Coal Basin, Poland, were examined using powder X-ray diffraction, electron probe microanalysis, inductively coupled plasma mass spectrometry, infrared spectroscopy and thermal analysis methods. The minerals occur as yellow, fine-grained crusts and botryoidal masses in the outer part of a sulphate crust found ∼1 m below the surface. The crust is composed mainly of godovikovite and tschermigite that formed by interaction of sour fire gases or solutions and waste materials beneath the surface of the burning coal dump at temperatures of at least 80—100°C. The crystals often reveal oscillatory zoning due to different Al and Fe contents in thin bands, from near end-members to extensive solid solutions. Our analyses suggest the existence in nature of a complete solid solution between ammonioalunite and ammoniojarosite. They also carry essential amounts of chlorine.

Despite their great potential, charred particles of chaff-and-straw temper from daub architecture have very rarely been considered as material suitable for 14C dating. This short paper is intended to change this situation. With this aim in mind, we first present the rationale and objectives of the sampling procedure based on archaeobotanical exploration of prehistoric remains of daub architecture, and then report and discuss the results of a short chronometric exercise based on such samples. The empirical verification of the sampling procedure was based on finds related to the epi-Lengyel culture from Upper Silesia.

The coal-bearing succession of the Upper Silesia Coal Basin consists of deposits filling a flexural foredeep basin. Accumulation initially compensated for regional and differentiated subsidence, after which the general depositional surface remained nearly flat. The deposition of the coal-bearing succession started at the end of Mississippian times (Pendleian Subage) and continued with hiatuses through almost the whole of Pennsylvanian times, and stopped in the Westphalian D Subage. The up to 8500 m thick coal-bearing succession traditionally has been divided into four main units called ‘Series’, and all of them are subdivided into subsidiary units known as ‘Beds’. The occurrence of the intervals containing marine faunas within the lower ‘Paralic’ part of the coal-bearing succession resulted from eustatic ingressions. The higher ‘Limnic’ part of the succession was laid down in fluvial systems, while the lower part was formed mostly in a fluvial and, to a lesser extent, complex coastal system. Sedimentation of the coal-bearing succession was controlled by both autogenic and allogenic factors.
