Императорская корона
With the secularization of Montenegro as a formal Princedom under Prince Danilo I Petrovic-Njegos, religious affiliation and even physical description of the passport holder were introduced as of the mid 19th century, in attempt to prevent fraud. The Seal was replaced with Danil's Coat of Arms, the lion was moved onto a red shield on the eagle's chest, while an Imperial crown was added.
