Philip III of Spain
Philip III (14 April 1578 – 31 March 1621) was King of Spain.
He was also, as Philip II, King of Portugal, Naples, Sicily and Sardinia and Duke of Milan from 1598 until his death in 1621.
A member of the House of Habsburg, Philip III was born in Madrid to King Philip II of Spain and his fourth wife and niece Anna, the daughter of Holy Roman Emperor Maximilian II and Maria of Spain.
Philip III later married his cousin Margaret of Austria, sister of Ferdinand II, Holy Roman Emperor.
Although also known in Spain as Philip the Pious, Philip's political reputation abroad has been largely negative – an 'undistinguished and insignificant man,' a 'miserable monarch,' whose 'only virtue appeared to reside in a total absence of vice,' to quote historians C. V. Wedgwood, R. Stradling and J. H. Elliott.
In particular, Philip's reliance on his corrupt chief minister, the Duke of Lerma, drew much criticism at the time and afterwards.
For many, the decline of Spain can be dated to the economic difficulties that set in during the early years of his reign.
Nonetheless, as the ruler of the Spanish Empire at its height and as the king who achieved a temporary peace with the Dutch (1609–1621) and brought Spain into the Thirty Years' War (1618–1648) through an (initially) extremely successful campaign, Philip's reign remains a critical period in Spanish history.

Maria Anna of Neuburg( 28 October 1667 – 16 July 1740), was Queen of Spain from 1689 to 1700 as the second wife of Charles II, last Habsburg King of Spain.

She lived largely forgotten until her death in 1740.

Maria Anna of Spain
Infanta Maria Anna of Spain (18 August 1606 – 13 May 1646) was a Holy Roman Empress and Queen of Hungary and Bohemia by marriage to Ferdinand III, Holy Roman Emperor.
She acted as regent on several occasions during the absences of her spouse.
Daughter of King Philip III of Spain and Margaret of Austria, prior to her Imperial marriage she was considered a possible wife for Charles, Prince of Wales; the event, later known in history as the "Spanish Match", provoked a domestic and political crisis in the Kingdoms of England and Scotland.
In the imperial court in Vienna she continued to be strongly influenced by her native Spanish culture (from clothes to music) and also to promote the strengthening of relations between the Imperial and Spanish branches of the House of Habsburg.
