Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

Eleonora of Arborea was a prominent figure in 14th-century Sardinia who led the giudicato of Arborea in its resistance against Aragonese rule following the death of her brother, Hugo, in 1383.1

Her most significant contribution to Sardinian governance was the perfection and promulgation of the Carta de Logu in 1392. Originally initiated by her father, Mariano IV, this comprehensive legal code served as a foundational framework for justice on the island. Its importance was such that Alfonso V of Aragon later extended the application of the Carta de Logu to the entire island, formalizing its role in Sardinian administration.1
