On 30th April 311, the Roman Emperor Galerius issued the world's first known Edict of Tolerance. Rome recognized the freedom of all Christians to worship and restore their churches with this edict. This public edict also influenced the second edict, which was expanded to cover all religions in 313. The foundations of the phenomena of tolerance are laid thanks to these two published Edicts of Tolerance.
The Tolerance Way begins at İzmit (Nicomedia), the period's capital on the date of the Edict of Tolerance’s publication and extends to İznik (Nikaia).
The route's exact starting point is the East Roman State Site in İzmit's center, and its exact ending point is the Hagia Sophia Mosque in İznik's center. The last eight kilometres of Tolerance Way intersects with Evliya Çelebi Way. The total length of the route is approximately 126 kilometres.
You may see more than 200 endemic birds in the bird paradise, as well as cultural and historical treasures, in the first part of the route. Besides that, the waterfalls, slopes, and beech trees in Beşkayalar Nature Park are also worth seeing.
