Luís de Meneses, 3rd Count of Ericeira

Luís de Meneses, 3rd Count of Ericeira (1632–1690), was a Portuguese nobleman, artillery general and historian who fought through the Restoration War, including the battles of Ameixial (1663) and Montes Claros (1665), and later wrote works on it.

He backed the party that deposed Afonso VI in 1667 and became finance minister under Pedro II. A Colbert-style mercantilist, he fostered Portuguese cloth and silk manufacture, settled foreign weavers in the interior, and secured protectionist sumptuary laws in 1677 and 1686. Troubled by melancholy, he killed himself at his Lisbon palace in May 1690.
