The Kingdom of Montenegro, in diplomatic relations, until the First World War, tried to be in equally good relations with Vienna, St. Petersburg and Rome. King Nikola I was a guest of Emperor Francis Joseph I at the Hofburg Castle couple of times, and once, in 1875, they met in Kotor. The arrival of King Nikola I via Njeguši – Kotor to the Montenegrin market, surrounded by soldiers and numerous Montenegrins who walked in traditional costumes was also recorded. On the train, on the way between Salzburg and Trieste, the king received the news of the Sarajevo assassination. His companion testified that he said “Here comes the war”. On the wave of the mood of people and faith in the allies, Montenegro declared war on Austria-Hungary.
