Blackseafor or Black Sea Naval Task Force is a multinational maritime force created in 2001 for the tasks of search-and-rescue operations, humanitarian assistance, mine countermeasures, environmental protection and goodwill visits in the Black Sea. Members include Turkey, Bulgaria, Georgia, Romania, Russia and Ukraine.
In 1998 former Turkish Navy Forces Commander, Salim Dervisoglu, purposed a maritime force of the Black Sea states. Dervisoglu brought his idea before experts and diplomats from the Black Sea states. The countries agreed to hold meetings with Black Sea Naval Commanders to plan an prepare for the operation. A total of ten meetings were held, and in 2000 the Black Sea states signed a letter of intent and sent it to the Turkish government( which gained authority of th region through the Montreux Convention). The Turkish government agreed to the force and in 2001 the initiative became official. In 2001, the operation's most important document,"The Blackseafor Establishment Agreement," was signed and the initiative began. Russia called on other members to expand Blackseafor's current mandate to include counter terrorismin 2004. Critics claim that this was in response to the United States interest in expanding NATO's counter terrorism mission, Operation Active Endeavour, to the Black Sea. Members continue to conduct regular training exercise and maritime missions through Blackseafor. In the future countries hope to expand Blackseafor to take over the Turkey's counter terrorism initiative, Black Sea Harmony. 
Blackseafor decisions are made by consensus of all members. The presidency of the alliance rotates in alphabetical order every year, Turkey was the first to have a president of Blackseafor. Like the presidency the headquarters also rotates. One maneuver, at least, most be carried out every year. The forces are specifically designed to cooperate with other international organizations such the United Nations, NATO, or the OSCE.
