What term describes a love for one's country and loyalty to that country?

The term that best describes a love for one's country and loyalty to that country is patriotism. Patriotism embodies the feelings of devotion, support, and dedication to the interests and culture of one’s nation. It is often expressed through participation in national events, the celebration of national symbols, and a commitment to the welfare and values of one’s country.

Nationalism, while sometimes overlapping with patriotism, generally refers to a strong identification with and pride in one’s nation, which can sometimes include the belief that one's nation is superior to others. Allegiance conveys loyalty but does not inherently carry the emotional connection synonymous with love. Allegory is a literary device used to convey meanings through symbolic figures and events, and it does not pertain to feelings for one’s country. Thus, the term that specifically captures the essence of both love and loyalty to one's country is patriotism.
