Spanish match in the context of "Diego Sarmiento de Acuña, conde de Gondomar"

George Calvert, 1st Baron Baltimore (/ˈbɔːltɪmɔːr/; 1580 – 15 April 1632) was an English politician. He achieved domestic political success as a member of parliament and later Secretary of State under King James I. He lost much of his political power after his support for a failed marriage alliance between Prince Charles and the Spanish House of Habsburg royal family. Rather than continue in politics, he resigned all of his political offices in 1625 except for his position on the Privy Council and declared his Catholicism publicly. He was created Baron Baltimore in the Peerage of Ireland upon his resignation. Baltimore Manor was located in County Longford, Ireland.

Calvert took an interest in the British colonization of the Americas, at first for commercial reasons and later to create a refuge for persecuted Irish and English Catholics. He became the proprietor of Avalon, the first sustained English settlement on the southeastern peninsula on the island of Newfoundland (off the eastern coast of modern Canada). Discouraged by its cold and sometimes inhospitable climate and the sufferings of the settlers, he looked for a more suitable spot further south and sought a new royal charter to settle the region, which would become the state of Maryland. Calvert died five weeks before the new Charter was sealed, leaving the settlement of the Maryland colony to his son Cecil. His second son Leonard Calvert was the first colonial governor of the Province of Maryland.

Maria Anna of Spain (18 August 1606 – 13 May 1646) was a Holy Roman Empress and Queen of Hungary and Bohemia by her marriage to Ferdinand III, Holy Roman Emperor. She acted as regent on several occasions during the absences of her husband, notably during his absence in Bohemia in 1645.

The daughter of King Philip III of Spain and of Margaret of Austria, she was prior to her Imperial marriage 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 promoted the strengthening of relations between the Imperial and the Spanish branches of the House of Habsburg.
