  1. 1.
    The tie or obligation, implied or expressed, which a subject owes to his sovereign or government; the duty of fidelity to one's king, government, or state.
  2. 2.
    Devotion; loyalty; as, allegiance to science.
    “Hear me, recreant, on thine allegiance hear me!” Shak.
    “So spake the Seraph Abdiel, faithful found, . . . Unshaken, unseduced, unterrified, His loyalty he kept, his love, his zeal.” Milton.
Syn. Loyalty; fealty.
Allegiance, Loyalty. These words agree in expressing the general idea of fidelity and attachment to the “powers that be.” Allegiance is an obligation to a ruling power. Loyalty is a feeling or sentiment towards such power. Allegiance may exist under any form of government, and, in a republic, we generally speak of allegiance to the government, to the state, etc. In well conducted monarchies, loyalty is a warm-hearted feeling of fidelity and obedience to the sovereign. It is personal in its nature; and hence we speak of the loyalty of a wife to her husband, not of her allegiance. In cases where we personify, loyalty is more commonly the word used; as, loyalty to the constitution; loyalty to the cause of virtue; loyalty to truth and religion, etc.
