(Viena, 1634 - 1696)
"Mariana de Austria (Wiener Neustadt, Austria, 22 de diciembre de 1634 - Palacio de Uceda, Madrid, España, 16 de mayo de 1696) fue reina consorte de España (16491665) como segunda esposa de Felipe IV y regente (1665-1675) como madre de Carlos II."
"Mariana of Austria (Spanish: Mariana de Austria) or Maria Anna (24 December 1634 16 May 1696) was the queen consort of her uncle Philip IV of Spain from their marriage in 1649 until Philip died in 1665. She was then appointed regent for their three-year-old son Charles II, and due to his ill health remained an influential figure until her own death in 1696. Her regency was overshadowed by the need to manage Spain's post-1648 decline as the dominant global power, internal political divisions and the European economic crisis of the second half of the 17th century. The inability of her son Charles to produce an heir led to constant manoeuvring by other European powers, which ultimately ended in the 1701 to 1714 War of the Spanish Succession. The Mariana Islands consisting of 14 islands in the northwestern Pacific Ocean are named after her."
