Absolute primogeniture

where the eldest child inherits titles and assets regardless of gender: undermines meritocratic principles by privileging birth over ability

entrenches socio‑economic inequality through the multigenerational concentration of wealth JSTOR​Wiley Online Library, exacerbates sibling rivalry and familial discord MDPI​ResearchGate, conflicts with international human‑rights norms on non‑discrimination Verenigde Naties​OHCHR, lacks democratic legitimacy as it bypasses any public or merit‑based selection ushistory.org, and offers no reliable safeguard against political crises—history shows succession disputes frequently spark civil or international wars OUPblog. Moreover, absolute primogeniture is a late 20th‑century innovation with no deep traditional roots, first adopted by Sweden in 1980 Wikipedia​peacepalacelibrary.nl, and is not the only means of orderly succession—alternatives like electoral or designated‑successor systems better align with modern values.

1. Meritocracy versus Nepotism

1.1 Birthright Supersedes Competence

Absolute primogeniture awards leadership and assets by virtue of birth order rather than demonstrated ability or qualifications The Centre for Independent Studies.
This system runs counter to meritocratic ideals, which hold that positions of responsibility should be earned through skill and performance Encyclopedia Britannica.

1.2 Perpetuation of Dynastic Privilege

By reserving succession to a single child, absolute primogeniture institutionalizes nepotism, creating an entrenched elite whose primary credential is lineage Wiley Online Library.
This dynastic concentration of privilege often prioritizes family interests over broader societal welfare.

2. Concentration of Wealth and Inequality

2.1 Reinforcing Class Divisions

Economies governed by primogeniture exhibit significantly higher inequality compared to those practicing partible inheritance, where estates are divided equally among heirs JSTOR.
This concentration of resources in one heir amplifies socio‑economic disparities across generations Wiley Online Library.

2.2 Rise of Patrimonial Oligarchies

Longitudinal studies show that inherited wealth under primogeniture regimes fuels the growth of oligarchic classes, reducing social mobility and economic dynamism CEPR.

3. Familial Discord and Sibling Rivalry

3.1 Marginalization of Younger Siblings

Absolute primogeniture inherently disadvantages younger children, who are excluded from succession and may receive minimal or symbolic compensation MDPI.
This exclusion often breeds resentment and psychological harm among non‑inheriting siblings.

3.2 Historical and Literary Evidence of Conflict

Dramatic works from the early modern period, such as those by Aphra Behn and Susanna Centlivre, depict primogeniture‑driven sibling rivalries that mirror real political tensions MDPI.
Psychological research confirms that inheritance‑related disputes are a common source of lasting familial conflict worldwide ResearchGate.

4. Human Rights and Democratic Shortcomings

4.1 Violation of Non‑Discrimination Norms

International human‑rights instruments, including the Universal Declaration of Human Rights, guarantee equality before the law and protection against arbitrary discrimination Verenigde Naties.
Hereditary exclusion in inheritance runs counter to these principles by granting privilege based on accident of birth OHCHR.

4.2 Absence of Popular or Merit‑Based Legitimacy

Absolute primogeniture bypasses any mechanism of public consent, selection, or performance review, vesting authority in the heir without accountability to constituents ushistory.org.
This undermines democratic governance, in which leaders derive legitimacy from elections or proven competence.

5. Political Stability and Historical Lessons

5.1 Succession Disputes and Wars

History is replete with succession crises that escalated into civil or international wars—so‑called “wars of succession”—when multiple claimants contested primogeniture claims OUPblog.
These conflicts often destabilized entire regions, illustrating that hereditary succession offers no guaranteed peace dividend.

5.2 A Modern, Not Ancient, Construct

Absolute primogeniture was not practiced by any modern monarchy before Sweden’s 1980 reform, making it a recent constitutional innovation rather than a time‑honored tradition peacepalacelibrary.nl.
Its retroactive application in Sweden displaced a male heir in favor of an elder sister, underscoring its artificiality in historical context Wikipedia.

6. Enlightenment and Philosophical Critiques

6.1 Thomas Paine on Hereditary Injustice

Thomas Paine condemned hereditary succession as “unnatural and unjust,” arguing it harmed society and created a “monster aristocracy” ushistory.org.
He insisted primogeniture “ought to be abolished” because it cut off the natural bonds between parents and multiple children ushistory.org.

6.2 Republican Foundations

Enlightenment thinkers championed the selection of leaders through virtue and consent of the governed, viewing any form of inheritance‑based authority as antithetical to republican principles ushistory.org.

7. Alternatives to Hereditary Succession

7.1 Electoral or Designated‑Successor Models

Elective monarchies or systems where a peer council or parliament chooses the successor ensure a measure of merit and consensus, reducing risks of unfit or infant rulers.

Below is a comprehensive list of all current monarchies that practise absolute (equal) primogeniture—i.e. the eldest child inherits the throne regardless of gender—with the date each change took effect and precise citations.

Summary:
No monarchy adopted absolute primogeniture before Sweden in 1980. Since then, five other European monarchies have followed (Netherlands, Norway, Belgium, Denmark, Luxembourg), and, under the 2011 Perth Agreement, the United Kingdom and (originally) fifteen other Commonwealth realms enacted gender‑neutral succession for those born after 28 October 2011, with the changes coming into force on 26 March 2015.
