One significant example of tolerance in the Ottoman Empire was the religious tolerance.
The Ottomans allowed the people that practiced Christianity and Judaism to continue with the practicing of their religious. They also enabled them to have their own temples and places of worship. This was a tactical move that worked out very well for the empire, because by allowing the people having their own faith, the empire was much more unified, peaceful, and stronger.
The religious tolerance did had some limitations though, such as the churches had to be lower than the lowest mosques in the places where they are built. Also, the Ottomans had the tendency to take away young boys from their families, rise and train them for the military, making them Muslim in the process.
