My former student Danilo Bozovic, now back home in Podgorica, shared this photo of Montenegrin flags in observance of Montenegro’s Independence Day. The referendum of 2006 was held on May 21 in that year, and since independence from Serbia was supported by 55.5% of voters, was followed by a formal declaration of independence on June 3, 2006. But it is the day of the vote that has become a public holiday.
