Croatia, officially the Republic of Croatia, is a country at the crossroads of Central and Southeast Europe, on the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east, Bosnia and Herzegovina, and Montenegro to the southeast, sharing a maritime border with Italy. Croatia is an ancient nation, yet a very young nation state. Once a formidable kingdom in the tenth century, a naval power in the sixteenth and seventeenth, and an awakening national entity in the nineteenth, it had to endure a thousand years of foreign meddling, subjugation, incursions, and outright wars before being recognized in 1992 as a distinct entity.
