House of Lara
On the death of his uncle, Juan Nunez de Lara the Younger in 1315, he became lord of the House of Lara, although his uncle, the late "Lord of Lara", had arranged in his will that all his possessions were sold and the proceeds from its sale should go to prayers for the repose of his soul. However, the noblemen of Castile unwilling to remain without a "Lord" asked the king to appoint Juan Nunez de Lara, despite his young age, master of the House of Lara. The King concurred and the noblemen gathered a sum of money that included land, castles and villas for the lordship of Lara. In 1326, his signature appears on some border privileges. A year after the death of Juan de Haro, Juan Nunez de Lara was named "Ensign of the King", and as such appears confirmed in his privileges from that year, ranking first among the nobility.
