One of the best period times that humanity had known by a lot of discoveries and expanding the knowledge was during the Islamic renaissance. It is also called the Islamic Golden Age that took place in Abbasid historical period beginning in the mid 8th century lasting until the Mongol conquest of Baghdad in 1258. I dream of living within those 400 years especially in Andalusia.
While Europe had ages of darkness Andalusia was the capital of knowledge in the world ,for example, royal dynasties
in Europe sent their Sons or daughters there to study and gain from that renaissance in that time. I like to start my education there and meet some of scientist who they established the knowledge or write the foundation of their fields. For instance, mathematician al-Khwarizmi the founder of algebra lived in that period and his knowledge used later to solve complex math problems.
What made Andalusia special in that time was a creative environment for any student. Also, the variety of knowledge that growing grammatically over there from Muslim or non-Muslim scholars was attractive for any student. In addition, I do not need to learn other languages because any new book will translate to Arabic quickly because the governor in that time gave each person who translate a book gold that equal to book weight.
In conclusion, there are several time in history that a person want to live there and see how life seem there.
