Mena's work may have achieved its propagandistic goals in the short-term. Mena presented the poem to the king in 1444 at a time of crisis, when Juan II was being held under house arrest by his rival cousins of Aragón and Navarra. Perhaps in part inspired by the poem, the king once again backed Luna, and this favorite reached his peak of power after the First Battle of Olmedo in 1445. Nevertheless, in 1453 Luna was beheaded by order of the king, and Juan II himself died not long after. Mena's final years were spent with the knowledge that his political goals had not, in the end, been achieved.
