At its height, the Pinkerton Agency's numbers exceeded those of the United States Army.[citation needed]

In 1991, Armenia declared independence from the USSR and established the second Republic of Armenia.

PROBLEM: Titles of honor that originated in the Middle Ages of Europe to designate a formally professed cavalryman is?, Context: Appointments to the Order of the British Empire were discontinued in those Commonwealth realms that established a national system of honours and awards such as the Order of Australia, the Order of Canada, and the New Zealand Order of Merit.

Canada, Australia, and New Zealand all have (in increasing level of precedence) Members of, Officers of, and Companions to (rather than Commanders of) their respective orders, with both Australia and New Zealand having Knights and Dames as their highest classes.

SOLUTION:
Knights
