The Deutsche Marine () is the navy of Germany and is part of the unified Bundeswehr (the German Armed Forces). It is deeply integrated into the NATO alliance. Its mission is protection of German and Allied territories as well as peace-keeping and peace enforcement operations. The Marine traces its roots back to the Reichsflotte (Imperial Fleet) of the revolutionary era of 1848 – 52. The Reichsflotte was the first German Navy to sail under the black-red-gold flag. Founded on 14 June 1848 by the orders of the democratically elected Frankfurt Parliament the Reichsflottes brief existence ended with the failure of the revolution and was disbanded on 2 April 1852; thus, the modern Marine celebrates its birthday on 14 June.
