What term names the lawsuits by Columbus's heirs against the Crown of Castile?

The lawsuits by Columbus’s heirs against the Crown of Castile were called the Pleitos colombinos.

The disputes centered on privileges Christopher Columbus believed the monarchy had granted him, especially offices, revenues, and authority connected with his discoveries. After Columbus died in 1506, his son Diego inherited his position as admiral and pursued the family’s claims against the Crown. The litigation began in earnest in 1508 and continued through multiple appeals, judgments, and related proceedings.

A first major judgment came at Seville in 1511. Later decisions were issued at La Coruña, Valladolid, Dueñas, and Madrid. The cases also included the pleito del Darién, which concerned how far the family’s jurisdiction extended on the American mainland.

In 1536, arbitration confirmed the hereditary admiralship and granted the heirs territorial and financial benefits, but removed their claims to the offices of viceroy and governor-general. The term should not be confused with the Requerimiento, the Laws of the Indies, or the Capitulations of Santa Fe, which were different legal texts or institutions.
