The present book, which was realized through the study of Persian historians and writers works, is an attempt to manifest the presence of the Portuguese in Iran during the Safavid dynasty. It provides a sequence of events, focusing on the role of Portugal in outlining the history of Iran in this period. The book is in two languages of Persian and Portuguese. The collected data, originally in Persian language, were compiled in a coherent order and was translated into Portuguese language, so that the interested readers or scholars, both the Persian and the Portuguese, can consult it.
