Factors and Consequences of Missing Historical Shiite Sources (Until the Seventh Century)

Based on the existing Pharaohs and the Rejali sources, there were a considerable number of Shiite sources, especially in the early centuries, which are not available now, with the aim of clarifying the answers to questions such as the reason for the depletion of Shiite historical sources and their consequences. What is? Also what is the answer to the question that is the most important reason for the loss of resources? And how effective was the Mongol attack on the loss of written sources, and is it a proper contribution to this event to waste resources? This research is organized. The hypothesis under consideration is the shift in attitudes among Shiite scholars that has fractured some of their possessions and weakened other works, and that is why important works have been lost. What this research has achieved is that the various spiritual causes, the most important of which are hypotheses, are physical causes as well as the causes of the destruction of these works; Is gone. Therefore attributing the loss of resources to merely the Mongol invasion is an unfinished story; and if those resources were available, it would make it easier for historians to cite historians as an important criterion for the validity of their research data, and their findings would have been more reliable and unnecessary to gain historical insights. The methodology of this descriptive-analytical research is based on library resources and the study of the remaining phases and bibliographies, as well as the scientists’ comments and their analysis and evaluation.
