Another notable figure was Alonso de Idiaquez (c. 1565-1638), a Spanish military commander and member of the prestigious Order of Santiago. He fought in several battles during the Eighty Years' War against the Dutch Revolt and was later appointed as the Governor of Milan in 1633.

In the 18th century, Ignacio de Idiaquez y Borja (1707-1768) was a Spanish nobleman and military officer who served as the Viceroy of New Granada (present-day Colombia and Panama) from 1763 to 1768.
