The reason why the Ottoman Empire blocked the eastern trade route

First, Osman is an Islamic country, and Islam opposes usury.

Second, I hope that heavy taxes will increase fiscal revenue.

Third, the feudal system objectively did not support the development of commerce. However, as a Turkic nomadic people, the Ottoman Empire was relatively low in feudalism.

Fourth, in order to confront European Christian civilization, I hope to harm its interests.
