Active in global affairs since the 9th century, modern Croatian diplomacy is considered to have formed following their independence from Yugoslavia in 1991. As an independent state, Croatia established diplomatic relations with most world nations – 187 states in total – during the 1990s, starting with Germany (1991) and ending most recently with Togo (2023). Croatia has friendly relations with most of its neighboring countries, namely Slovenia, Hungary, Montenegro, and Italy. They maintain colder, more tense relations with Serbia as well as Bosnia and Herzegovina due to historic nation-building conflict and differing political ideologies.
