Sure. I don't have the necessary knowledge to correct these sections. The most egregious error is the following statement: "His system of government, which may be described as a benevolent despotism, was perhaps that best suited to the character of his subjects." This passive construction raises the questions: benevolent for whom? described by whom? It implies that the Montenegrins were unable to govern themselves and needed a wise father to gently raise them into civilization. If this is true, it needs a citation, but I'm sure there were plenty of trade unionists and republicans who disagreed at least slightly ;-)

The following phrases read as excessively fawning, slightly biased or perhaps just worded in an old-fashioned style:

"the young highlander, whose keen patriotism, capability for leadership and poetic talents early displayed themselves, showed no inclination for the pleasures of the French capital, and eagerly looked forward to returning to his native land."

"He gave Montenegro its first constitution in 1905 following pressure from a population eager for more freedom."

"King Nikola was gifted with a fine physique and a commanding presence, was a successful military leader and a graceful poet"

I hope this helps so that someone who has the knowledge to do the edits can update the article accordingly.
