Miguel de Noronha, 4th Count of Linhares

He became 4th Count of Linhares when his cousin in the third degree, Dom Fernando de Noronha, died childless in 1608.

As his father, Afonso de Noronha, he was governor of Tangier between 1624 and 1628, gaining several successes in struggles with the Moors in that region.

During his reign in India, Miguel was confronted by serious problems with corruption and external attacks, which led to important losses in Portuguese Ceylon and Mombasa.

This led to serious confrontations with Olivares, who felt that all dominions of King Philip IV of Spain should be Spanish provinces.

As a reward for his loyalty, he was appointed General of the galleys of Sicily and Spain, and raised to Marquis de Gijón and Duke of Viseu.
