Excerpts from Books and Wikipedia
"Croatia (population: 4.2 million), an EU member since 2013, has a long coastline on the Adriatic that has recently become a major European tourist destination. In the long and bitter aftermath of the collapse of Yugoslavia, relations with neighboring Serbia are still strained, and the presence of a Croatian minority of about 600,000 in neighboring Bosnia continues to stir a range of political sensitivities."
