The consequences of climate change could be so severe and extensive that the issue has prompted human societies to change their subsistence system and adopt strategies to deal with those challenges. In the past, droughts and the reduction in water resources caused serious problems for human societies and made it difficult for water-dependent communities to continue living in a specific region and area. In order to get out of the crisis, many communities either migrated to favorable areas or attacked other communities. In the second millennium BC, Central and West Asia witnessed large-scale human migrations and violent invasions, which apparently overlapped with climatic stresses. The extensive migration of Aryan tribes and predatory invasions of the Sea Peoples in Egypt, Levant, Anatolia, and Greece during the second half of the second millennium BC coincided with the 3.2 ka BP mega drought event. This research, with an environmental archeology approach, actually tries to warn about the unfortunate consequences of global warming, i.e. climate migrations and social tensions. Here, the reason for population displacements and attacks on civilizations in the second millennium BC has been investigated from the climatic perspective. The Paleoclimate research indicates frequent climatic events in the early Late Holocene in Central and West Asia, which probably triggered many socio-political events.

Biological samples such as bones, tooth, and hair obtained from archaeological excavations are mainly used for dating measurements. However, these findings provide valuable information about the diet, lifestyle or migration, and genetic interaction of communities, and disease because the biochemical content of biological tissues such as bones, teeth, and hair changes under the influence of the lifestyle of the past population. Therefore, it seems that human remains' biochemical, microscopic, and histological studies could be advantageous for clarifying the dark events of the past societies. Bioarchaeology, as an interdisciplinary science, assesses the historical-cultural relationships in ancient samples and human remains like hair, bone, or tooth by biological tools and techniques. In this science, the biological data of specimens are combined with archeological information to obtain a more accurate sociology of past civilizations. The purpose of the present review article is to familiarize archeology researchers with the usual methods in bioarchaeological studies.

In a survey carried out in the Sadrabad area of ​​Zarandieh in June 2020, in addition to the whole village of Sadrabad, its satellite areas were also examined and identified, which led to remarkable results in the archaeological studies of the Iranian plateau, which in addition to other archaeological survey, metal slags were also studied and analyzed there. Slag is the residue of minerals from the smelting, which occurs naturally as a molten silicate or as a mixture of several silicate minerals with compounds of oxides, sulfides, and metals. To detect metal minerals in slag, it is necessary to prepare a polished section from the samples in order to identify its  type . The silicate minerals in the slag are studied with  passing light using a thin section. Gazanak Zarandieh Tepe is located 85 km from Tehran and 75 km from Saveh in Sadrabad Vilage in Zarandieh city of Markazi province. The oldest settlement phase identified in this area is Neolithic (or Pre-pottery Neolithic) and the newest period identified is related to the Safavid era. In this survey, we obtained evidence of smelting and processing of copper, which included pure native copper and slag from smelting of this metal, which by integrating them for laboratory studies, especially the petrographic elemental analysis, which resulted in amazing results. The purpose of petrographic testing on study samples is to identify the components of the slag, the type of material extracted and, if possible, the host rock mineral. Since the study area lacks Chalcolithic age, and the abundance of plum ware, which appeared in the context of Cheshmeh Ali pottery and the transition period according to the speculation of the 2021 season, led us to the question that melting and extraction copper metal in the center of the Iranian plateau has an older history than the dates presented in this article.

In 1994, it was reported that a group of smugglers had been arrested while excavating the hills of Hossein Abad, south of Susa, about 800m south of an area called Siahchal (Donjon). That excavation led to the revelation of half of a stone coffin or a sarcophagus and eventually led to the discovery of two more sarcophagi, which were located 2.5m from each other. The first sarcophagus was constructed in the form of a tomb with bricks of lion stamp patterns. Both sarcophagi are made of sandstones. The mine of these stones does not appear to have existed in Susa. However, the older fabric of Susa had instances of a sand mass, with underground cellars created inside these stones. Hence, the stones from which the sarcophagi were built could probably relate to Susa. No objects or human skeletal representing burial remnants were recovered from inside of the sarcophagi; however, out of Sarcophagus No. 1, some pieces of earthenware and perfume containers (Alabaster) were found. The bricks used in Tomb No. 1 were bearing lion patterns, as the pieces of earthenware and marble perfume bottles, numerous examples of which were reported from there, demonstrate they could reasonably be attributed to the Achaemenid dynasty.  

The Sistan region has played a prominent role in establishing and expanding civilization in the eastern region of Iran in different historical periods. The region’s favorable environmental conditions, including abundant water, fertile soil, and diverse flora and fauna, attracted various ethnic groups to settle and achieve significant advancements by constructing numerous cities and settlements. Over its documented existence, Sistan with a rich collection of historic buildings and archeological sites has experienced three periods of extensive settlement and three periods of non-settlement, commonly referred to as gap periods. Multiple factors have contributed to the development of Sistan socially and settlement wise. This article aims to identify the influential factors in the cycle of formation and collapse of civilizations in Sistan by examining geographical, historical, and archaeological factors. Among these, water availability, political considerations, and other natural and human-related aspects stand out as the main contributors to this cyclic pattern.

Fakhr al-Dīn Muḥammad ibn Manṣūr Mubarākshāh al-Qurashī was born around 1150 CE, probably in Ghazna, and eventually joined the court of Quṭb al-Dīn Aybak, the first Turkish Mamlūk or “Slave King” of northern India. He died around 1224 CE. His Ādāb al Ḥarb wa’l Shujācah (“Rules of War and Bravery”) was a treatise on statecraft in the Persian tradition of “Mirrors for Princes”. A substantial, if idealised discussion of warfare, it includes sections on tactics, troop organisation, various weapons, sieges and many military-historical anecdotes. Nevertheless, these chapters also include more recent, more localised Indian and Turkish elements, plus otherwise lost aspects of military practice or theory. For example, the essentially traditional Islamic or ʿAbbāsid sections include Chapter 12 which describes “How to arrange an army firmly and to maintain that (arrangement)”. The first part of Chapter 13 describes “How to bring the army to a halt and the (best) place to do this”. Some specifically military chapters of theĀdāb al Ḥarb wa’l Shujācah are clearly based upon ʿAbbāsid military theory as developed during the 8th to 10th centuries CE; notably sections such as “How to arrange an army firmly and to maintain that (arrangement)”, and “How to bring the army to a halt and the place to do this”. Other sections reflect more recent Indo-Islamic, Indian and Turkish military ideas, as well as otherwise lost aspects of earlier military practice, plus plans of military arrays, idealised encampments and exercises in the tradition of Islamic furusīyah military training manuals. Chapter 11, which is interpreted here, concerned the characteristic features, advantage and usage of a wide array of weapons. Chapter 19, which is also interpreted here, focussed on various aspects and variations in the array and deployment of an army for battle.

The lifeways of mobile human societies are a field investigated by anthropologists and archaeologists. Mobility is considered an effective way of foraging and resource production among human societies (for hunter-gatherers, pastoralists, and farmers, respectively). Various classifications regarding the mobility patterns of human societies have been proposed so far. As of today, the majority of archaeologists use Murdock’s multi-purpose classification which divided mobile human societies into four groups: (1) Nomadic societies, (2) semi-nomadic societies, (3) semi-sedentary societies, and (4) sedentary societies. But some societies have characteristics that do not allow them to be placed in one of these groups. For identification of these unclearly defined societies, the authors will refer to 5 criteria of demographic dimensions: Mobility, number of movements, movement distance, residential criteria, and lifeway. For instance, it was not until 2003 that archaeologists began to recognize the intermediate trajectory of nomadic pastoralism from early village-based herding to the formation of full-fledged pastoralism in the western part of Central Zagros. Extensive study of pastoralist communities, however, can be used for the identification of several intermediate stages of the 5 criteria. Current archaeological evidence in most of the early Neolithic sites in Central Zagros such as Qazanchi, Sheikhi Abad, Sarab, Asiab, and Guran, unlike the Levant region which was settled in the Epipaleolithic (Natufian) period, indicates that these sites are seasonal. So how can we explain the mobility of human societies in the proto-Neolithic period of Zagros? As a result, the authors try to use these criteria to identify the intermediate stages of sedentarism in Zagros, from mobile societies in the Epipaleolithic period to sedentary societies in the late Neolithic period. For this purpose, the authors have studied the mobility patterns and residential criteria of human societies in the cultural landscape of Hawraman. The research was conducted in two seasons, in the summer of   2016 and the summer of 2018, respectively. At first glance, the patterns of mobility and lifeways of human societies seemed homogeneous and identical in the cultural landscape of Hawraman. But with a deeper analysis, Four main mobility patterns were identified. The patterns include (1) single-stage agriculturalist residential mobility in Koh-e-Takht, (2) multistage pastoralist residential mobility in Kosalan and Shahu Mountain, (3) logistical mobility (transhumance) in Javeh River, and (4) logistical mobility (based on cultural exchanges) all over the Hawraman. The patterns show that the Zagros societies did not become sedentary in a single stage. Therefore, semi-sedentary societies with residential mobility and semi-sedentary societies with logistical mobility can be placed in the intermediate stages.
