        Nehbandan County is considered one of the important areas in the archaeological research of the historical and Islamic period of South Khorasan. The eastern region of Shah Kouh in the west of this county, due to the existence of suitable and favorable climatic and land conditions, contains important and spacious settlements, which shows their importance in intra- and extra-regional interactions in historical times. Among these unique monuments, there are the remaining parts of the building known as Atashkadeh (Fire Temple) in the village of the same name, but unfortunately, only a few parts of this structure are left. According to the results of the excavation project to determine the core zone and suggest the buffer zone of the building as well as the existing architectural evidence and the current architecture in the context of the village, it is believed that this structure was founded with a cruciform pattern and four stone walls and a dome cover. The study shows that this building was built in the Sassanid period and was still standing in the early Islamic centuries as a religious place and in connection with the surrounding sites. Here, some of the nearby sites such as Kalate Bal Batu and Taska Cemetery were introduced and their surface cultural remains were also discussed and analyzed. This research aims to recognize the Fire Temple building according to the archaeological evidence and also to introduce other sites of the historical era such as Klate Bel Beto and Taska. Collecting the findings has been conducted in the field and analyzing them through Library research has been done with a historical-cultural approach and descriptive-analytical method.

        2 - Nizamabad: its position in the end of the classical period of Iran to the beginning of the Islamic period

        Passing from the Sasanian era to the Islamic era, the culture and art of Iran continued in its previous way and few changes occurred in it. One of the key archeological sites next to Tepe Hisar and Chal Tarkhan (and some other sites), which shows the transition from Sasanian to the early Islamic era, is Nizamabad. Despite this importance, the location of this hill has been shrouded in mystery and most researchers have noted it near Varamin or Ray. However, according to the photograph taken by Ernst Herzfeld in 1925 of Nizamabad, it can be identified by morphology. Nizamabad is located in the southwestern of the Tehran. In this article, by introducing this hill, we are trying to show its importance so that proper planning can be done for future research activities. Fortunately, there has been minimal encroachment on this hill -in the southeast of Islamshahr- and although it has been registered in the list of national monuments of Iran, the area and boundaries have not been determined. Considering the importance of the unique plaster casts of this hill in museums, measures should be taken to protect the hill. Manuscript profile

        Pottery is the most abundant and one of the most important archaeological materials, which can be used by Archaeologists for the purposes like dating, specifying the technological and socio-political complexity level of various human groups, artistic transitions and study of economic and cultural interactions between past societies. Therefore making acquaintance with this material culture and presenting more and more exact classifications is a basic, but of high importance work to be done in the archaeological recognition of past societies. Yet, unfortunately our archaeological knowledge of the Sasanian ceramics is negligible. Finding a large number of Sasanian shards from the archaeological survey of Farsan County in Chahar-mahal & Bakhtiari province, the present paper deals with description, typology and comparison of Sasanian ceramics from this county. Based on that, it has been specified that Sasanian Pottery of Farsan has the clear similarity with acquired samples from the neighboring cultural zones of Khuzestan and Fars which according to the dynastic character of Sasanian political system, geographic specifications of the region and the prevailing livelihood mode of nomadism of these societies make sense. The results of this research gave a new sight to the interaction between the under study region, which is lying at the crossroad of southwest, west and central plateau routs of Iran, and neighboring regions during Sasanian era.

        With the rise of Islam and the conquest of Sassanid cities by Muslims, the fate of political, economic, religious and physical structure of these cities were greatly changed. This article explains spatial changes created with the rise of Islam in Sassanid cities based on the case study of Bishapour. The results show the breakdown of the Sassanid class system in the social structure of the city. That means in the early centuries of Islam, because of equality and Islamic brotherhood, texture of the city was changed and in quantitative terms, there was strong growth in housing of the poor class and lower class accede to elite spaces that previously belonged to upper class in Sassanid city. Social discrimination derived from Zoroastrianism disappeared largely from Bishapour in Islam period. With the increase in Muslim population and the power of rulers and the establishment of Islam in the country and relative security, Islamic thinking and worldview shows itself clearly in the urban spatial structure in the late third and fourth centuries. Arrangement of buildings in urban spaces and the urban spatial structure in Islamic period changed according to Islamic ideology and necessities. At the same time buildings such as Grand Mosque, Madrasa (school), Caravansary and Bazaar entered the urban context. In conclusion it must be said, urbanism in Islamic period, is created from transformation of the urban spaces of Sassanid period under the influence of Islamic thought. Manuscript profile

        Throughout history, there were several nations forced to speak other languages and to learn about other cultures as a result of war, migration, religious beliefs, and so on. This fusion of language and culture has led to the emergence of many artistic styles and forms. This was a reciprocal influence on the culture and art of both countries or all the countries involved in the specific historic event such as war, migration, etc. Archaeological excavations carried out by Professor Ed Keele and a Canadian archeological team at Yazdgerd castle before the revolution of Iran revealed a critical column that contained a number of motifs. After a while, the column was moved to the ROM Museum in Toronto.In this article I provide reference to evidence and documents form pasts centuryes to present, and I would make this argument that one of these motifs can be an obvious representative of a dancer or a singer. This paper includes a piece from my lifelong research in the field of theatre and show form.The article explains how the carved details in the form and cover of this excavated motif are very similar to Gusan and maybe Krishna, the Indian god. There are several historical Books that talk about Gusans as pioneers of acting in the world. The hypothesis explains how this mural can be perceived as a typical role of a Gusan. A proposed explanation is provided as to how the prominence of a Gusan can adorn the palace of a king. Manuscript profile

        Mādayān ī hazār dādestestān or Book of a Thousand Judgment is the only manuscript of the imperfect from the legal collection of the Sassanid period. This article is studying a legal term tōzišn means paying the debt and paying the debt of the deceased and compenasting of the warranter and pēš-tōzišnīh the meaning of repayment and how the debtor's debt is settled and its purpose is to explain the legal rules to pay of the debt of the deceased and how to settle the debt in the civil society of the Sassanid period. For this purpose, a question arises: What did the legislators envisage in the issuance of Judgments tōzišn and pēš-tōzišnīh to pay the debt and settle it? Based on the existing laws, we find that, Legislators with awareness predicted possible disputes of survivors in the death of the deceased and the debtor's possible evasion of payment and even the debtor's financial poverty and issued rulings for pay the debt of the debtor and pay the debt of the deceased, duties of survivors, the debtor and guarantor are know; and disagreement is eliminated between the family and the legal creditor and by adopting legal solutions, does not exist way to avoid fulfilling the obligations. This article is theoretical and has been done with historical-analytical method. While interpreting the legal term tōzišn and pēš-tōzišnīh, we find its social function in the Sassanid period. Given the lack of documented research in this area, the need to address it is obvious. Manuscript profile

        Hamadan, as one of the oldest cities in Iran, and the center of the Median state, which undoubtedly has been the "heart of Iran" in popular thought since the Achaemenid era in terms of geography. In the late Sassanid era, it was easily subjected to invasion, and with its conquest by the Muslims, Islam came to this city. This study attempts to examine the process of forced or compulsory entry of Islam into the city of Hamadan and attempts to reject the theory of forced acceptance of Islam by Hamadan people on the one hand and to criticize the idea of easy acceptance of Islam by Hamadan people. This study examines the following: (a) The people of Hamadan have shown strong resistance to the Arabs, but this does not mean that Islam has also been forced into the Hamadan culture. B) The Islamisation of the Hamadans has not been rational and deliberate everywhere, but other psychological, social, economic and political factors have also influenced their Islamization. C) Adoption of Islam did not necessarily mean acceptance of Arab culture, but the core of Islam as a text (Qur'an) penetrated among the Hamadans, and they were able to understand this revelation, and finally to fit it with their human possessions and to mix it with the truth.

        In the Sassanid era, religion became the government and political and social structure was one-sided, religion was completely at the service of politics. The corrupt system of Mobdan justified the actions and behaviors of the oppressive kings, the class system and the shortcomings of the Sassanid era society. They faced a comprehensive and complete religion that emphasized equality, justice and equality. This research aims to investigate the religious factors of the defeat of the Sassanids against the Muslim Arabs with a critical approach using a descriptive-analytical method and using library sources and existing documents. Therefore, based on the results of the research, the religious factors that were effective in the defeat of the Iranians from the Arabs can be pointed to the chaotic conditions of the Sassanid era, the influence and power of the clerics or Mughans in the Sassanid era. Regarding the religion of Zoroastrianism in the Sassanid period, it should be known that this religion revolved around one axis of the Avesta book. This book was not a book containing mere religious rules, but had the status of a large encyclopedia, which included various sciences and also the clergy of the Zoroastrian religion. They were removed from the initial state. Iranshahri thought, the occurrence of wars such as Dhi Qar, religious policies of Sassanid clerics against Jews and Christians, and the emergence of Islam, are among the religious and religious factors effective in the defeat of the Sassanids from the Arabs.

        By the Sassanid government, Ardeshir Babakan chose Ctesiphon as the capital. This city played a significant role in creation of the country’s political unity and turned it into a political, economic, and social center. Due to locating on important commercial and trade routes, such as the Silk Road and the Persian Gulf Sea to the Indian Ocean, Ctesiphon was politically and strategically of particular importance in Mesopotamia. At the end of the Sassanid government, given the turbulent political, economic, and social situation, Ctesiphon lost its initial prosperity. In terms of trade and commerce, the Sassanid capital played the key role in international relations since the Iranian cities were the trade and industry center during the Sassanid era. Given the kings’ frequent comings and goings in the last years of the Sassanid government, political and military instability in Ctesiphon led to turmoil in the capital and other subordinate states as well as revolts of the states’ governors and rulers in various parts of the country. Research method: In the present paper, based on its theoretical nature, the historical, explanatory, and analytical research method is employed and library method is used for collecting data. The present paper is aimed at explaining the Ctesiphon’s role and position in the political and economic equations of the Sassanid era. Manuscript profile

        The architecture of Sasanian era is, in fact, continuation and development of Parthian architecture and, at the same time, reminiscent of Achaemenid architecture. By the formation of Sasanian empire, Iran’s society began to thrive, and by articulation of a precise, effective plan regarding urban development, architecture, and industrialization of the society, it absorbed the attention of civilized Roman and Hellenistic world. The culture and art of Sasanian followed those of Achaemenid and Parthian. Sasanians tried to catch up with the Achaemenid culture. They showed their hegemony relative to prior eras in the arts of architecture, sculpture, plastering, and building domical arches as well as pillarless, vast halls. In architecture, reliefs, and sculptures of Sasanian era, differences and similarities, particularly in the topic and content, are seen compared to those of Achaemenid era. Sasanian dynasty founder, Ardashir I was the governor of Darabgerd, Pars before taking the throne and founded it and Gaur city, also known as Firuzabad, circularly based on the traditional architecture of Parthian era. In this article conducted with analytical-descriptive method, questions like “what were the building method, materials, and functions of buildings in Sasanian era?” and “what was its difference with Achaemenid architecture?” will be answered.

        Beyond the central deserts of Iran, Sistān and Khorāsān formed the eastern states of the Sasanian Empire, which were considered rich and economically prosperous states at the time. On the other hand, although the neighborhood with the eastern nomadic tribes the dangers it posed to their inhabitants but had given them a strategic aspect. Besides, it affected the events of these states extremely. Hence, the Economic, Political, and social situation studies of this region, particularly in the last half-century of the Sasanian dynasty, which finally ended in the downfall of their dynasty, can be considered important. The present study intends to find out the effects that the Economic, Political, and social situation of the Sasanian eastern states had on the fall and conquest there by the Muslim Arabs based on library resources using a descriptive-analytical research method. The research findings suggested that the invasion of nomads and forced migrations to the eastern Sasanian states caused diversity in the demographic composition; there. This factor, along with their lack of political and economic dependence on the central government, doubled the incentive for achieving power among local rulers; Eventually, they caused the fall of the Sasanian dynasty.
