Jus Aesneciae

Jus Aesneciae is a Latin term that refers to the right of primogeniture. This means that the eldest son has the right to inherit the entire estate of his father, to the exclusion of his younger siblings.

For example, if a father has three sons and he dies without leaving a will, the eldest son will inherit everything, while the younger sons will receive nothing. This is because of the principle of jus aesneciae.

Another example is the British monarchy, where the eldest son of the reigning monarch is the heir to the throne, regardless of whether he has any older sisters or younger brothers.

These examples illustrate how jus aesneciae works in practice, where the eldest son is given priority over his siblings in matters of inheritance and succession.
