The Muslim conquest of the East in the seventh century entailed the subjugation of Christians, Jews, Zoroastrians and others. Although much has been written about the status of non-Muslims in the ...Islamic empire, no previous works have examined how the rules applying to minorities were formulated. Milka Levy-Rubin's remarkable book traces the emergence of these regulations from the first surrender agreements in the immediate aftermath of conquest to the formation of the canonic document called the Pact of 'Umar, which was formalized under the early 'Abbasids, in the first half of the ninth century. The study reveals that the conquered peoples themselves played a major role in the creation of these policies and that they were based on long-standing traditions, customs and institutions from earlier pre-Islamic cultures that originated in the worlds of both the conquerors and the conquered. In its connections to Roman, Byzantine and Sasanian traditions, the book will appeal to historians of Europe as well as Arabia and Persia.
It would seem unlikely that one could discover tolerant religious attitudes in Spain, Portugal, and the New World colonies during the era of the Inquisition, when enforcement of Catholic orthodoxy ...was widespread and brutal. Yet this groundbreaking book does exactly that. Drawing on an enormous body of historical evidence-including records of the Inquisition itself-the historian Stuart Schwartz investigates the idea of religious tolerance and its evolution in the Hispanic world from 1500 to 1820. Focusing on the attitudes and beliefs of common people rather than those of intellectual elites, the author finds that no small segment of the population believed in freedom of conscience and rejected the exclusive validity of the Church.
The book explores various sources of tolerant attitudes, the challenges that the New World presented to religious orthodoxy, the complex relations between "popular" and "learned" culture, and many related topics. The volume concludes with a discussion of the relativist ideas that were taking hold elsewhere in Europe during this era.
Since the beginning of its history, Islam has encountered other religious communities both in Arabia and in the territories conquered during its expansion. Muslims faced other religions from the ...position of a ruling power and were therefore able to determine the nature of that relationship in accordance with their world-view and beliefs. Yohanan Friedmann's original and erudite study examines questions of religious tolerance as they appear in the Qur'an and in the prophetic tradition, and analyses the principle that Islam is exalted above all religions, discussing the ways in which this principle was reflected in various legal pronouncements. The book also considers the various interpretations of the Qur'anic verse according to which 'No compulsion is there in religion …', noting that, despite the apparent meaning of this verse, Islamic law allowed the practice of religious coercion against Manichaeans and Arab idolaters, as well as against women and children in certain circumstances.
Religious intolerance, so terrible and deadly in its recent manifestations, is nothing new. In fact, until after the eighteenth century, Christianity was perhaps the most intolerant of all the great ...world religions. How Christian Europe and the West went from this extreme to their present universal belief in religious toleration is the momentous story fully told for the first time in this timely and important book by a leading historian of early modern Europe.
Perez Zagorin takes readers to a time when both the Catholic Church and the main new Protestant denominations embraced a policy of endorsing religious persecution, coercing unity, and, with the state's help, mercilessly crushing dissent and heresy. This position had its roots in certain intellectual and religious traditions, which Zagorin traces before showing how out of the same traditions came the beginnings of pluralism in the West. Here we see how sixteenth- and seventeenth-century thinkers--writing from religious, theological, and philosophical perspectives--contributed far more than did political expediency or the growth of religious skepticism to advance the cause of toleration. Reading these thinkers--from Erasmus and Sir Thomas More to John Milton and John Locke, among others--Zagorin brings to light a common, if unexpected, thread: concern for the spiritual welfare of religion itself weighed more in the defense of toleration than did any secular or pragmatic arguments. His book--which ranges from England through the Netherlands, the post-1685 Huguenot Diaspora, and the American Colonies--also exposes a close connection between toleration and religious freedom.
A far-reaching and incisive discussion of the major writers, thinkers, and controversies responsible for the emergence of religious tolerance in Western society--from the Enlightenment through the United Nations' Universal Declaration of Human Rights--this original and richly nuanced work constitutes an essential chapter in the intellectual history of the modern world.
For Native Americans, religious freedom has been an elusive goal. From nineteenth-century bans on indigenous ceremonial practices to twenty-first-century legal battles over sacred lands, peyote use, ...and hunting practices, the U.S. government has often acted as if Indian traditions were somehow not truly religious and therefore not eligible for the constitutional protections of the First Amendment. In this book, Tisa Wenger shows that cultural notions about what constitutes "religion" are crucial to public debates over religious freedom.In the 1920s, Pueblo Indian leaders in New Mexico and a sympathetic coalition of non-Indian reformers successfully challenged government and missionary attempts to suppress Indian dances by convincing a skeptical public that these ceremonies counted as religion. This struggle for religious freedom forced the Pueblos to employ Euro-American notions of religion, a conceptual shift with complex consequences within Pueblo life. Long after the dance controversy, Wenger demonstrates, dominant concepts of religion and religious freedom have continued to marginalize indigenous traditions within the United States.
Efforts to understand autoimmunity have been pursued relentlessly for several decades. It has become apparent that the immune system evolved multiple mechanisms for controlling self-reactivity, and ...defects in one or more of these mechanisms can lead to a breakdown of tolerance. Among the multitude of lesions associated with disease, the most common seem to affect peripheral tolerance rather than central tolerance. The initial trigger for both systemic autoimmune disorders and organ-specific autoimmune disorders probably involves the recognition of self or foreign molecules, especially nucleic acids, by innate sensors. Such recognition, in turn, triggers inflammatory responses and the engagement of previously quiescent autoreactive T cells and B cells. Here we summarize the most prominent autoimmune pathways and identify key issues that require resolution for full understanding of pathogenic autoimmunity.
Improving SO2/H2O resistance at low temperatures is a key challenge for industrial applications of NH3-SCR catalysts. Herein, a novel catalyst with remarkable low-temperature NH3-SCR activity and ...strong SO2/H2O resistance was designed by loading MoOx protective layer over porous kit-CeO2. The in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) coupled with basic characterization techniques were utilized to further elucidate the underlying mechanisms, and a dynamic balance between the deposition and decomposition of ammonia bisulfate was captured over porous kit-CeO2. Highly dispersed MoOx species pre-adsorbed with NH3 significantly curtailed the adsorption of NOx molecules, and the catalytic reaction over MoOx/kit-CeO2 primarily followed by the Eley-Rideal mechanism. At 250 °C, in the presence of SO2 and H2O, the Ce-O-Mo pairing site was almost unaffected and the super SO2- and H2O-tolerant property originated from the facilitated decomposition of ammonium bisulfate (ABS) and the shielding effect of Mo protective layer on SO2/H2O. This study provided an important guidance to the application of ceria-based catalysts for environmental control within low-temperature operations in non-power industries such as glass, steel, cement manufacturing, etc.

Eliminating cytoreductive conditioning from chimerism‐based tolerance protocols would facilitate clinical translation. Here we investigated the impact of major histocompatibility complex (MHC) and ...minor histocompatibility antigen (MiHA) barriers on mechanisms of tolerance and rejection in this setting. Transient depletion of natural killer (NK) cells at the time of bone marrow (BM) transplantation (BMT) (20 × 106 BALB/c BM cells → C57BL/6 recipients under costimulation blockade CB and rapamycin) prevented BM rejection. Despite persistent levels of mixed chimerism, BMT recipients gradually rejected skin grafts from the same donor strain. Extending NK cell depletion did not improve skin graft survival. However, F1 (C57BL/6×BALB/c) donors, which do not elicit NK cell‐mediated rejection, induced durable chimerism and tolerance. In contrast, if F1 donors with BALB/c background only were used (BALB/c×BALB.B), no tolerance was observed. In the absence of MiHA disparities (B10.D2 donors, MHC‐mismatch only), temporal NK cell depletion established stable chimerism and tolerance. Conversely, MHC identical BM (BALB.B donors, MiHA mismatch only) readily engrafted without NK cell depletion but no skin graft tolerance ensued. Therefore, we conclude that under CB and rapamycin, MHC disparities provoke NK cell‐mediated BM rejection in nonirradiated recipients whereas MiHA disparities do not prevent BM engraftment but impede skin graft tolerance in established mixed chimeras.
This article shows that in nonirradiated mice, major histocompatibility antigen barriers are mainly responsible for NK cell–mediated bone marrow rejection under costimulation blockade and rapamycin while minor histocompatibility antigen barriers determine donor skin graft survival.

How the plasma membrane senses external heat-stress signals to communicate with chloroplasts to orchestrate thermotolerance remains elusive. We identified a quantitative trait locus,
Thermo-tolerance ...3
(
TT3
), consisting of two genes,
TT3.1
and
TT3.2
, that interact together to enhance rice thermotolerance and reduce grain-yield losses caused by heat stress. Upon heat stress, plasma membrane–localized E3 ligase TT3.1 translocates to the endosomes, on which TT3.1 ubiquitinates chloroplast precursor protein TT3.2 for vacuolar degradation, implying that TT3.1 might serve as a potential thermosensor. Lesser accumulated, mature TT3.2 proteins in chloroplasts are essential for protecting thylakoids from heat stress. Our findings not only reveal a
TT3.1-TT3.2
genetic module at one locus that transduces heat signals from plasma membrane to chloroplasts but also provide the strategy for breeding highly thermotolerant crops.
Heat tolerance in rice
Too much heat can damage a plant’s chloroplasts, driving yield down when temperatures exceed a crop’s normal tolerance. Zhang
et al
. identified a locus with two genes that together enhance rice thermotolerance. The ubiquitin ligase activity of Thermo-tolerance 3.1 (TT3.1) drove degradation of TT3.2, a chloroplast precursor protein that can trigger chloroplast damage in the context of heat stress. Together, these protein products respond to heat and control the damage. —PJH

There are adaptive T-cell and antibody autoimmune responses to myelin-derived peptides in multiple sclerosis (MS) and to aquaporin-4 (AQP4) in neuromyelitis optica spectrum disorders (NMOSDs). ...Strategies aimed at antigen-specific tolerance to these autoantigens are thus indicated for these diseases. One approach involves induction of tolerance with engineered dendritic cells (tolDCs) loaded with specific antigens. We conducted an in-human phase 1b clinical trial testing increasing concentrations of autologous tolDCs loaded with peptides from various myelin proteins and from AQP4. We tested this approach in 12 patients, 8 with MS and 4 with NMOSD. The primary end point was the safety and tolerability, while secondary end points were clinical outcomes (relapses and disability), imaging (MRI and optical coherence tomography), and immunological responses. Therapy with tolDCs was well tolerated, without serious adverse events and with no therapy-related reactions. Patients remained stable clinically in terms of relapse, disability, and in various measurements using imaging. We observed a significant increase in the production of IL-10 levels in PBMCs stimulated with the peptides as well as an increase in the frequency of a regulatory T cell, known as Tr1, by week 12 of follow-up. In this phase 1b trial, we concluded that the i.v. administration of peptide-loaded dendritic cells is safe and feasible. Elicitation of specific IL-10 production by peptide-specific T cells in MS and NMOSD patients indicates that a key element in antigen specific tolerance is activated with this approach. The results warrant further clinical testing in larger trials
