Changes

Battles are often decisive moments in history that prove one direction or path in history could be undertaken based on the outcome. This was the case at the Battle of Qadisiyyah, where the Islamic army was able to not only triumph but the results of the battle allowed them to surge into what is today Iraq and gain a new confidence and finance their campaigns that helped propel their expansionother expansions. The results probably would have been very different if the battle was lost by the Arab army, as the Sasanian Empire would have been in better position to then dominate the Middle East. Religion and language changes are the most visible outcomes from the battle's significant results. However, the results also influenced how the Arabs eventually created contacts with Europe, where important Classical works and philosophy was transferred back to Europe, including new developments in Persian and Arab sciences and philosophy, that helped to launch the Enlightenment centuries later.
