Synonym: 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. 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)
