Constitutional Standing and Succession
The Spanish Constitution of 1978 and the Historical Memory Law govern succession. As the firstborn child of the reigning monarch, Leonor is the immediate heir presumptive. Should she marry and have children, they would follow her in the line of succession. If she were to have a younger brother, he would not displace her, as absolute primogeniture has been in place since 1978. If she ascends to the throne, she will become Spain’s third queen regnant, after Queen Isabella I and Queen Christina of Spain.
Order of Succession (Simplified)
