Well, we were taught in school that Peter was a great reformer. That he centralized power in Russia, created a navy, reorganized the army, and strengthened the state. As for the institution of the patriarchate, it should be noted that the more secular power the church has in a country, the more backward that country is. However, I will not engage in a debate on the latter issue, as my further arguments will definitely offend the religious feelings of representatives of many denominations.
